High-pressure valves from SKG Pneumatics Inc

High-pressure valves are manufactured according to the latest international designs, using the latest advanced technology and a strict quality control system. These valves are exceptionally robust, robust, and durable. They are designed for a waterproof seal, ease of use with integrated quality and integrity for long service life. SKG Pneumatics Inc is specializing in firefighting equipment and industrial valves suppliers. If you are searching for industrial valve suppliers then your search destination ends with SKG pneumatics.

High-pressure valves are manufactured in Gate and Globe valve types.

  • Gate valves: It is the most common valves in use today, especially when the uninterrupted flow is required, as the valve fully retracts into the bonnet, creating minimal pressure drop when the valve is in the open position. Gate valves usually are intended for use in isolation applications.
  • Globe valves:   The main advantage is that a globe valve opens faster than a globe valve because the disc only needs to move a short distance from its seat to allow full flow. It is an advantage in case of frequent valve operation. The disadvantage is that the fluid has to change course, which increases the resistance to flow and generates turbulence. It results in a higher pressure drop through a globe valve than a gate valve. Globe valves are designed to close, open, or restrict flow in a pipeline.
  • The pressure seal cap:   Another very effective type of cap construction, apart from the standard bolted cap type in a gate valve, is the seal cap. This construction is adopted for valves for high service at very high pressure. The unique feature of the pressure seal cap is that the seal of the body-cap seals improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-cover gasket.

SKG pneumatics is the topmost reputed firefighting equipment dealer and has been top-ranked in manufacturing & supplying high-pressure valves for many years.

Applications of High-pressure Valves

  • Boilers of steel industries:- In Iron and steel industries where boilers are used at high pressure, high-pressure valves are essential to keep safety at the workplace. 
  • Power plants and Chemical factories:- Certain chemicals are stored at high pressure as they can be dangerous at low pressure. Hence using reliable and efficient high-pressure valves can decrease the risk factor.
  • In sugar factories:- Manufacture of sugar involves high pressure in the boiler which can easily be regulated using high-pressure valves. Our valves can function properly in water, aggressive environment as they are made from chemically inactive material and do not contaminate or react with the fluid passing through them.

Importance Of PRESSURE REDUCING VALVES

Many times, the people complaints about the water pressure because the water is not coming out enough for them so, SKG PNEUMATICS the leading Suppliers of Industrial Valves presents The Pressure Reducing Valve (prv) is the most popular safety equipment designed to safeguard the pressurized system through the period of overpressure. The correct water pressure is important to have a better hot shower that is tough to beat. If you need to reduce the water pressure in the ball valve then you can use the PRV. The main purpose of this valve is life protection by venting the gas or fluid from the high pressurized vessel.

Causes of high water pressure

The municipal water supplier is a major reason for having high water pressure. According to the area where people live, the city controls the pressure of water. They are making sure that high water pressure is enough to reach the tallest buildings and other things such as water towers, fire hydrants, Hydrant valves & Landing valve, and others. The water pressure level can be set between 100 and 200 psi to get water to a tall building. For residential buildings, the water pressure is 50 psi if you need to test the water pressure in your home then you can buy a water pressure gauge or otherwise contact the local plumber to check the water pressure level.

Tricks to fix the high water pressure 

Do you need to control the high water pressure in the home? Well, you are landed in the right destination. Here you can get a solution to control high water pressure. The water pressure relief valve is an ideal choice to control the water pressure. It is attached to the water pipe that is installed next to the water meter in the residential place. In the market, there is a large range of pressure to reduce valve. You can select the right valve such as Butterfly Valves, Check Valves & Non-return Valve which fit your requirements. This type of valve looks the same to small the bell that aids to control the level of pressure coming from the mains of water and into the plumbing system of the property with a screwdriver.

Application of high water pressure

The pressure relief valve is the most popular type of pressure control valve. It is utilized to keep constant pressure in the water pipe where the water flow is unstable. With the help of the valve, you can reduce the pressure level in a certain location of the systems. The pressure reducing valve is used for different purposes such as air compressor, Oxyfuel welding and cutting, mining industries, aircraft, aerospace, and much more.

Other types of pressure relief valve

In the market, you can find different kinds of pressure relief valves such as safety valve, vacuum relief valve, Balancing valve and much more. The safety valve is the best pressure relief valve actuated that used for air as well as stream service. The balanced relief valve is the pressure that reduces the valve that reducing the effect of the back pressure on the opening and closing pressure.

The pressure reducing valve plays an important role when it comes to reducing the pressure level in the pipeline. The reducing valve is the vital valve adjusting screw and spring in the pipe. The operation of a reducing valve can be controlled by high pressure at the inlet of the pressure valve.  The pressure relief valves are used for the protection of water hammer below accurately defined conditions.

The pressure regulator is one of the valves that help to control the gas or fluid pressure in a particular valve. It refers to any condition that causes pressure to improve beyond the identified design pressure in the system. It is always said the buy these type of valves from a reputed company i.e  SKG PNEUMATICS the leading Suppliers of Industrial Valves

What is Valve Automation? 

Industrial valves are mechanical devices that are used in various industries to control the flow of fluids and gases. 

Valve automation is the process of adding a valve actuator and control system to the valve and can be powered by electric, human, hydraulic, or pneumatic energy. 

Just like valves, there are different types of valve automation.  

Types of Valve Automation

  • Manual: There are various ways to use valve automation via manual energy. This includes hand wheels, levers, and gears. Since it is manually operated, it isn’t as costly as other methods. However, it is impossible to operate larger valves manually because of the high thrust requirements. There can also be a safety issue if the valve is located in remote or hazardous environments. 
  • Pneumatic: Pneumatic valve actuators use gas or air pressure as its power source to turn the valve on or off. Because of their simplistic design, they require minimal maintenance. Besides, they can be even used in areas with extreme temperatures. 
  • Hydraulic: Much like Pneumatic valve actuators, hydraulic valves use fluid pressure as its power source. Hydraulic actuators are suited for high-force applications, and they can produce more significant force than pneumatic actuators of the same size. 
  • Electric: The electric actuator converts electrical energy into torque to operate the machine. Out of the four types, electric valve actuators offer the highest precision control positioning. Besides, they are non-toxic, quiet, and energy-efficient. They are expensive and not ideal for applications that require high speed or failure modes. 

Difference between Valves & Actuators

If you have worked with industrial valve suppliers, you might know that both valves and actuators play a crucial role in automating process control. 

A valve is used to control the amount of fluid flowing through a pipe/machine. However, you must

A valve is used to control the amount of fluid flowing through a pipe/machine. However, you must set it either in a specific position or control it manually. Actuators, on the other hand, is controlled by a computer system that uses different sensors which dictate the action of the actuator and therefore the valve.

Uses of Check Valves & Non return Valves

Both check valves and non-return valves serve the same purpose, i.e., prevent the fluid from flowing back. Though they serve the same purpose, they are not the same. Let’s have a look at both of them in-depth. 

Check valves

A check valve is a mechanical device used in hydraulic systems to stop the flow of the fluid in one direction and allow free flow in the opposite direction. Unlike other valves, check valves do not require assistance to open and close. They even work if the plant loses electricity or air. Most common types of check valves are:

  • Swing type

    • Top hinged
    • Tilting disk

  • Lift type

    • Piston type
    • Ball-type

  • Dual Plate type

  • Stop Check valve

Non-return valves

A non-return valve is a mechanical device that is used to ensure that the fluid flows in the right direction, where pressure conditions might reverse the flow. Non-return valves are usually operated manually. Most common types of non-return valves are:

  • Spring-loaded non-return valves
  • Clapper type non-return valves

Difference b/w check valve & non-return valves

While many manufacturers consider check valves and non-return valves as the same thing, it is not actually the same. Check valves prevent backflow in defined circumstances, and it has to meet very strict criteria to ensure fluids are not able to siphon back into the systems. Whereas non-return valves need not meet the strict guidelines as check valves. 

Applications of check valve & non-return valves

Check valves and non-return valves are most commonly used in hydraulic systems and pumping stations. Other applications include:

  • Wastewater management
  • Portable water management
  • Irrigation
  • Mining 
  • Food and beverage
  • Oil and gas
  • Pharmaceutical
  • Power plant

Both check valves and non-return valves help:

  • Protect equipment downstream from backflow damage
  • Prevent contamination due to reverse flow
  • Prevent siphoning
  • Keep a vacuum seal

Pneumatic Butterfly Valves

Butterfly valve is typically used for the regulation of fluid flow. It is most widely used for supply of water for fire protection, for industries related to fuel and chemical along with various other applications. Unlike the ball valves, butterfly valves actually operate with single quarter-turn mechanism. There are various types of butterfly valves which can be found in the market today.

Butterfly valve is basically based on the principle of quick shut off. It functions with a disc in the center pipe which permits a small rod to pass through it to the actuator which is present on the external side of the valve. The valve allows the flow of fluid when the user rotates the disc with a quarter turn. It is also known as the quarter-turn valve. The valve gets its name from the metal disc attached to the rod which helps in permitting the flow of fluid with a quarter turn and also helps in blocking the passage. This disc, which is often called as the butterfly is the most part of this form of valve.

The best butterfly valve that you can use depends on your purpose of using the valve. It has gained quick popularity in the industry due to its easy to start, stop and regulating feature.

You can get four different types of butterfly valves in the market.

  • Motorized Butterfly Valve:   

    This type of valve is used widely for controlling the flow of fluid via a pipeline. It operates by simply altering the position of the round disc which is present with a system pipeline. You can use this type of valve for pipeline o any size as they are available in various sizes and specifications which you can choose according to your need.

  • Concentric Butterfly Valve:

    This type of valve is used for the regulation of low-pressure pipelines. This can be installed very easily and will also provide with the 100% efficiency. This type of valve is the lightest of all.

  • Wafer-Type Butterfly Valve:

    It is very easy to use type of valve but it fails to function as the valve for isolation.

  • Pre-insulated Butterfly Valve:

    This type of valve is the most durable out of all and are resistant to cracks.

Solenoid Valve – Working process of solenoid valve

A solenoid valve is an electro-mechanical valve that can be used to control the flow of liquid or gas. The main components of the solenoid valves consist of a valve stem, valve disc, valve body, valve boot, valve seat, stop washer, centring washer, plunger, coil, and a cover nut. It is commonly used in hydraulics & pneumatics to shift two way and 3-way directional control valves and some pressure control valves. The basic function of the solenoid valve is to shut off, distribute, and release fluid.

Working process of the solenoid valves

The main functional components of solenoid valves are the coil, plunger, and sleeve assembly. When the orifice in the solenoid valve is open, then it allows the flow of fluid. However when it is closed, then it prevents the flow through the valve. To open the orifice of a solenoid valve plunger is used, which raises or lowers within the sleeve tube by energizing the coil. Once the solenoid coil is energized, the resultant magnetic field raises the plunger, enabling the flow. When the solenoid coil is energized in a normally open valve, the plunger seals off the orifice, which in turn prevents flow.

Application of Solenoid valves

  • Hydraulic action:- Solenoid valves are designed specifically for controlling hydraulic operations effectively.
  • Controlling air pressure:- Solenoid valves are used for mixing and distributing the air effectively and hence, effectively control the air pressure.
  • Treatment of water:- As it can purify the smallest particles and dust, they can be used effectively in the RO purifier as well.
  • Fuel supply: – A solenoid valve is used in fuel valves to control the oil in vehicles. Highly efficient solenoid valves are leak-proof and can control the flow of oil effectively.
  • Blood analysis instrument:- Solenoid valves are also used in blood analysis instruments. These instruments need to control the flow of the blood properly, and solenoid valves are designed specifically for this purpose.
  • Machines and plant engineering:- Solenoid valves are commonly employed in manufacturing companies or oil refineries. They are often used to control the temperature of heater or furnace, firing systems, etc.

Highly Durable and Reliable Solenoid Valves

Features of Solenoid valves

It consists of a movable armature made of an iron alloy and attached to the valve needle, all sealed into the valve body. The coil is wound around the valve housing that contains the armature.

Difference between Pressure Relief Valves and Pressure Safety Valves

A pressure relief valve is one that is used to limit the pressure in a system within a specific set level. However, a pressure safety valve actuates automatically to release excessive pressure. Relief valve opens only when the pressure reaches the specific set pressure limit and is usually operated by an operator. It does not require operator assistance to release excessive pressure.

The similarity between the pressure relief valve and the safety valve is that they both are spring-loaded valves. Usually, the valve is forced shut by the spring. When the pressure increases, the force of the spring has overcome that forces the valve to open.

Classification of the Pressure Relief Valves

Pressure Relief Valves are essential for controlling the flow rate of fluid, thereby facilitating the practical use of the system and providing additional safety to pressurized vessels or systems. There are three types of Pressure relief Valves.

  • Safety valves: – A pressure valve that is used with compressible gases, steam, and air services.
  • Relief valve: –  A valve that is used in a hydraulic system as pressure over sill devices. They can further be into adjustable relief valves and safety relief valves. They are usually used in naval ships for generating thermal electricity.
  • Safety Relief valve: – A valve that is used either for liquid or compressible fluids in a pressurized vessel is called a safety relief valve. These are generally used in boilers.

Classification of Safety Relief Valves

  • Conventional(spring-loaded):- The main components of traditional spring-loaded safety relief valve are the nozzle, seat disc, disc holder, bonnet, spring, set pressure adjusting screw, body, and blowdown adjustment ring.
  • Pilot operated:-  The main component of pilot-operated hydraulic valve is inlet from the system, orifice, main spool spring, dart, pilot spring, adjustment screw, pilot drain, the skirt of the spool, and
  • Balanced bellows:-  The essential components of Balanced bellows relief valve are nozzle, body, adjusting ring, disk, seating surface, bellows, balanced piston, bonnet, spring, adjusting screw, stem, and cap.

SKG Pneumatics is the best supplier of industrial valves in Delhi. The company has been into pneumatic industries for several years. The company manufactures different types of relief and safety valves that can be used in the industrial production unit. The pressure safety relief valve can prevent damage to property, life, and environment to a great extent and shall be used in every industry for additional safety. The pressure relief valves can be used in pressurized vessels, boiler, and other pressurized systems.

Heating, Ventilation, and Air Conditioning System (HVAC)


Since all the mechanical systems that provide thermal comfort and air quality in a room/indoor area are interconnected, they are often grouped together and are called HVAC systems. It includes central air conditioners, heat pumps, boilers, furnaces, rooftop units, chillers, and packaged units.

HVAC valves are used to control flow in pipes. Major components of an HVAC system such as water chiller, cooling water pumps, air handling units, and fan coil units use valves to control the flow of water, gas, and air.

What is HVAC System?

HVAC is the acronym for Heating, Ventilation, and Air Conditioning. HVAC refers to the various systems that are used along with heating and cooling buildings (both commercial and residential). An HVAC system is responsible for keeping you fresh and cool in summer and making you feel warm and cosy in winter. Apart from just keeping a place warm or cool, HVAC systems are also responsible for improving indoor air quality while providing comfort to everyone inside the building.

What are the different types of valves used in HVAC System?

Plug valves (seat valves), ball valves, and butterfly valves are the most common types of valves used in heating, ventilation, and air conditioning system. Other valves used in HVAC system include knife gate valves, diaphragm valves, and gate valves.

Heating and cooling Hydronics-triple duty valves acts as a check valve, shut-off valve, and balancing valve all at the same time. Automatic flow limiting valves are used to vary the speed pumping systems that control the flow of the water in HVAC systems while automatic temperature control valves are used to reduce the temperature of the water in the domestic hot water pipe.

A pressure reducing valve is used to reduce the pressure of the water in the HVAC hydronic loop while circuit setter valves are used to maintain a set amount of flow through a piping loop.

HVAC systems not only regulate the temperature of the indoor space but also maintain the indoor air quality. However, it is important to use high-quality industrial valves in order to get the best results.

SKG PNEUMATICS INC is the leading industrial valve suppliers in India. In fact, all their valves go through multiple ruggedness-testing procedures to ensure that their customers receive the best industrial valves.

Applications and Working process of Control Valve


A valve is a device that regulates the fluid flow as well as the pressure within a system or process. Unlike on-off valves, a control valve is used to regulate the fluid flow by stopping and starting the fluid flow as per the direction is given by the controller.

Control Valve

Control valves consist of three main parts: the valve, the actuator, and the controller. Various components of the Actuator include rain cap, eye bolt, diaphragm, spring, actuator stem, diaphragm case, scale plate, stem connector, and yoke.

The components of body part include packing flange, packing follower, yoke claim nut, gland packing, valve stem, bonnet, stud bolt and nut, gasket, guide ring, guide bushing, valve plug, seat ring, valve body, trim set, and positioner.

Though the primary purpose of a control valve is to regulate the fluid flow, there are two main forms of action i.e. the sliding stem and the rotary action. The most common type of control valves in the sliding stem include globe valve, angle body valve, and angle seat piston valve while the rotary action includes a butterfly valve and ball valve.

Why Control Valves are Used?

Control valves are used for various purposes in the industrial, engineering, manufacturing, and scientific communities. The primary purpose of a control valve is to regulate the rate of the fluid flow by varying the size of the flow passage. Control valves are most commonly used for consequential control of process quantities including pressure, temperature, and the liquid level.

How do Control Valves work?

With the help of opening and closing internal passages, control valves regulate the fluid flow. Control valves form a control loop which is then used by a controller to send signals. Control valves respond to these signals and adjust the internal openings accordingly.

Control valves use the actuator to move the valve stem. Usually, it is either air (pneumatically) or electrically driven. The pressure between the inlet and outlet decides the rate of flow through the valve.

In order to reduce the fluid flow, the valve is closed, which results in more back-pressure and increases the difference between the inlet and outlet pressures.

Control valves help in controlling the fluid flow and are used in various industries including pipeline, oil & gas, food & beverage, the biopharma industry, and marine industry.

SKG PNEUMATICS INC is the top industrial valve suppliers and they are also the leading control valve suppliers in India. All their products are tested for resilient durability to provide the best industrial valve to their customers.

How does it work: Gate Valves

Gate valves are the most common valves found in the distribution system. Gate valves are mostly used for the on/ off control. Gate valves prevent the flow of the liquid in both directions. They are very easy to install and to maintain. Gate valves are cost-efficient and they are mostly used in petroleum industries because of their abilities to cut through liquids. 

What is a Gate Valve?

A gate valve is a linear motion valve that is used to start or stop the flow of the fluid in piping. There is a gate or wedge type disk which moves perpendicular to the flow which directs the flow to stop or start. In any process plant, the gate valve has the most common use and are suitable for both above-ground and underground installations. 

A gate valve is also known as a sluice valve. It is very easy to open it, one just have to lift the gate out of the path of the fluid. It does not require a wide surface; it fits in a very little space along the pipe axis. It requires a 360° surface contact between disk and seat to achieve proper sealing. A Gate valve is made up of certain parts that allow it to function properly. Valve’s body or shell is the most principle part of this particular valve which can connect the inlet and outlet pipes in a piping system. 

What are the different applications of Gate Valves?

Mainly it is used for all kinds of applications and it is the best fit for all types of above ground and underground applications.

  • It is mostly used when the pressure loss is minimum and when the free bore loss is needed.
  • It can be used for numbers of fluids and it is suitable for potable water, wastewater and neutral liquids 
  • The temperature is required between -20 and + 70-degree centigrade for which the velocity of the flow should be 5 m/s and up to 16 bar differential pressure. 

 

What is the working principle of the Gate Valve?

There is a handle wheel on the top of the gate valve and when this wheel will be rotated in a clockwise direction, the steam and gate will move in the downward direction. It prevents the leakage of fluid through the valve.

When the wheel is rotated in the anti-clockwise direction, the valve will be opened and the steam and gate will move in the upward direction across the fluid. The gate valve can also be used in the semi-opened direction but the erosion of gate as fluid will strike and hence it is not recommended to open it partially.
