The Advantages, Application & Components of Butterfly Valves

A butterfly valve considered as a regulating device which is used to shut off the flow of a fluid. It is also known as quarter turn valves because it provides 90-degree rotary motion for the stoppage. They often came in large sizes but short in length and are of the very lightweight. They possess very low torque requirements. It is used with globe and ball valves in some applications. 

Advantages

Butterfly valves are the best choice for all kinds of butterfly valve requirements. These are very cost effective and the performance of the product is also very high. These valves are similar to ball valves but have a little more advantages. The dist in the butterfly valve is lighter than a ball and it requires less structural support than a ball valve. Butterfly valve does not require high maintenance and hence widely used in industrial applications. They also require a little space and it is very easy to open them. 

Components

There are four main components of a butterfly valve: body, disk, stem, and seat.

1. Butterfly valve body

The body of the butterfly valve fits between two pipe flanges. It is one of the main components of the butterfly valve. Lug and wafer body design are most common among them.

2. Butterfly valve disk

The disk is used to stop the flow of the liquid. The disk of the butterfly valve has a number of variations in its design and orientation to improve the flow, sealing or torque.

3. Butterfly valve stem

 It is available in two design one- piece shaft or two-piece design. For the proficient selection of the material with respect to its cost as well as mechanical properties, it is confined from the media.

4. Butterfly valve seat

It provides the shutoff between the disk edge and the seat. Elastomers and polymers are used to make the seat of the butterfly valve. It may be bonded with the body or may be locked in.

Applications

Some of the common applications of the butterfly valve are: 

On/ off isolation, Dead- end service, heating, ventilation, and air conditioning system, Industrial process piping, Municipal raw water intake, Municipal chlorinated water systems (2000 ppm), Municipal feed water and reservoir, throttling and process control, full vacuum, blower installations.

How Fire Sprinkler System Work?

Fire is an ultimate nightmare for those who run a store or warehouse. Just imagine your building is stocked with furniture and other flammable items and a fire breaks out at night when no one is around. No need to worry we are here with a fire- fighting system which can react the moment trouble strikes. It has a sounding alarm and an automated sprinkler system to put out a fire as quickly as possible. Fire sprinklers are not for business use only they are also worth having in homes. This is one of the best fire protection systems which have protected life and property for over 100 years.

A fire sprinkler system seems to be a simple system made up of pipes with sprinkler head that deliver water to a fire. But it is a complex system that is carefully designed, installed and tested. An automatic fire sprinkler system works when high heat triggers the sprinkler system. The air above the sprinkler heats rapidly when a flame ignites. When this hot air reaches a sprinkler’s head, it triggers a chain reaction. The sprinkler is filled with a glycerin-based liquid expands when it comes in contact with the hot air and the sprinkler head activates. A fire sprinkler system is ready to install after the designing process.

Fire system installation process is quite simple and it is done by the pipe fitters at the construction site. There is a need of commercial sprinkler system in commercial buildings as a fire could seriously injure or kill employees or customers, damage property, destroy paper records. A fire sprinkler system makes your business safer. The automatic fire sprinkler system detects the fire and it is far way better than the spray that is used to extinguish the fire.

So if you are also willing to make your business safer than automatic fire sprinkler system is the right choice for you. SKG Pneumatic Inc is the one stop destination for complete range of industrial products. We are one of the leading fire fighting equipment suppliers. You can contact us for any kinds of fire equipment.

Functions and Applications of Automatic Balancing Valve


Automatic balancing valves are used in heating and cooling systems where water flows through the system. Balancing valves are used to ensure the correct distribution of water flow within the system. Water flows from one system to another. When water is flowing in this way it is possible that the pressure is not consistent enough. This can lead to an inconsistent output. To control and regulate these valves are used.

Functions of balancing valves

When Check Valves & Non-return Valve are used in hydronic systems, it ensures a proper design flow within the system leading to a better working of the cooling system where it is being used. Apart from this the other functions of automatic valves are:

  • They work as pressure independent control valves and help to limit flow to achieve the desired rate of flow.
  • It is an automatic valve and does not require manual intervention. This makes it simpler to use and there is no dependence on external persons.
  • Ensures the best flow rate that can improve the efficient working of the system.
  • Valves help to eliminate vibration and noise from the system where they are used.
  • Automatic valves help to achieve better temperature control and cooling is more effective.
  • Since it is automatic in nature, there is no need for a person to be employed to physically operate the valves, thus it leads to savings in terms of labor and time – this translated to savings in money.
  • Easy addition of additional devices to the system without having an effect on balance.

Uses and applications of balancing valves

Automatic control valves have many uses and applications. It is commonly used in applications like:

  • It is used in HVAC (Heating Ventilation Air Cooling) systems used in large commercial and residential buildings to ensure temperature control.
  • It is used in chilled ceilings where a cooling effect has to be produced.
  • It can even be used in fan coil units.
  • It can be effectively used in any heating or cooling system where a balanced flow is needed.

Installation

Automatic balancing valves are very useful devices used in most cooling systems. When an organization wishes to buy and install these valves, they need to make sure they get it from one of the leading suppliers of Balancing valve. A well-known manufacturer and supplier would ensure quality in the valves. Durability and reliability are what one needs to look at while buying these valves.

Pressure Reducing Valves – Applications & Installation

Pressure Reducing Valves or more commonly Water Pressure Reducing valves lower the pressure of in rushing water/ steam/fluid to a manageable and predetermined level usually at a constant level to make it safer. Utilized in residential, commercial, institutional, and industrial installations the downstream pressure is ensured through a pressure adjustment valve setting. The modern models also incorporate an external sensor for the same purpose. Similarly, the Pressure Independent Control Valve (PICV) includes a tiny diaphragm type DPCV to ensure a constant differential pressure across the opening such that a constant flow rate is maintained.

Pressure reducing valves are categorized into two types — direct acting and pilot operated. These employ globe or angle style bodies. Direct-acting valves have gained more popularity as they comprise globe-type bodies with a spring-loaded, and a heat-resistant diaphragm linked to the outlet valve that connects a spring. The spring, on the other hand, presets tension on the valve seat that is a pressure-equalizing mechanism in order to gain precise water pressure control.

INSTALLATION STEPS FOR PRESSURE REDUCING VALVES  

  1. Determine first the inlet water pressure. Attain it BY ATTACHING  A PRESSURE GAUGE TO HOSE SILL Cock. Ideal house water pressure should be measured at around 50 PSI.
  2. In case pressure exceeds excessively, install the pressure-reducing valve.
  3. Using threaded pipe and fittings, attach a pressure gauge, an initial step to the pressure-reducing valve at each side.
  4. Place the pressure-reducing valve assembly against water pipe to draw the mark for cutting the pipe.
  5. After Shut off the water mains, drain water from the piping system.
  6. Employ a tubing cutter for removing a water pipe section, from the marks made in Step 4.
  7. Remove from valve assembly both the pressure gauges and rubber O-rings.
  8. Brush flux the valve assembly ends onto the ends of the water pipe.
  9. Solder valve assembly to the water pipe as part of the piping system that is made of copper.
  10. Reinstall the pressure gauges and O-rings, after assembly cools.
  11. After turning on the water take a reading of the pressure gauge placed on the outlet side of the valve.
  12. In case water pressure is above 50 PSI (too high), the adjusting screw on the valve should be turned counterclockwise.
  13. On the other hand in case the water pressure is less than 50 PSI ( too low )  the adjusting screw on the valve should be turned clockwise.

 

The same installation can follow all similar steps including pressure control valve, water prv.

In hydraulics, a pressure reducing valve serves the same purpose as a pressure regulator valve in a compressed air system and will lessen the pressure in one branch but enable full system pressure operations at other branches. Installed directly after the water meter in homes, commercial buildings, and industrial plants, a ( water) pressure reducing valve automatically reduces the pressure to a lower, more utilizable pressure from the main supply.

SOME OF ITS APPLICATIONS ARE:-

  • Protecting electric hot water storage heaters and household appliances
  • Building and domestic installations
  • Collective installations
  • Industrial installations

TYPES OF BUTTERFLY VALVES AND DEMAND

POPULAR BUTTERFLY VALVES

When it comes to the butterfly valve, there are four types including Wafer type end, lug type ends, butt welded type ends and both flanged ends. They have a wide demand in several industries like sugar, oil, chemical industries etc. Butterfly valves, mainly the wafer valves and lug type valves are always tested to meet industrial requirements.

DIFFERENCE BETWEEN WAFER AND LUG TYPE VALVES

The wafer body type valve is easy to install but cannot be used as the isolation valve. They don’t have attachment lugs. On the other hand, Lug type valves have lugs attached to the flanges on the end and can be removed easily.

DEMAND OF BUTTERFLY VALVES

Butterfly Valves are in high demand because these valves can be used even in high-pressure services. Butterfly valves need less time to open and close, thus maintenance costs compared to other valves like ball valves.

ADVANTAGES OF BUTTERFLY VALVES

Due to its lightweight design and compact nature butterfly valves is suitable as compared to other valves. They are most popular and high in demand among the Valves Suppliers in Delhi.  They can be widely used in cooling water, fire fighting, vacuum services with good performance.

OTHER TYPE OF BUTTERFLY VALVES EXCEPT FOR THE WAFER AND THE LUG

While the wafer type cannot be used as a pipe end, lug type can be used as a pipe end. The other two form of butterfly valves mainly the welded one is used for high-pressure applications.

With the demand of valves growing in the Indian market other valves like balancing valves, a globe valve, ball valve has also increased. Although, butterfly valves still remain the most popular particularly because of its low cost and easy installation.
