Hydraulic Valves – Types and Components

A mechanical device that controls the flow of the liquid, usually by opening and closing is referred to as a valve. The primary purpose of a hydraulic valve is to direct the flow of a liquid medium that will move actuators and loads through the hydraulic system. There are various types of hydraulic valves and it is important to choose the right one to get the best results. 

What are the different types of hydraulic valves?

Hydraulic valves come in a variety of sizes and with different mounting styles. There are three major categories of hydraulic valves namely directional control valves, pressure control valves and flow control valves. 

Directional Control Valves

The primary purpose of a directional control valve is to control the direction of the fluid flow. The three functions performed by directional control valves include stopping the fluid flow, allowing the fluid flow, and changing the direction of the fluid flow. 

There are five types of directional control valves:

  • Check valves
  • Shuttle valves
  • Two-way valves
  • Threeway valves
  • Fourway valves

Pressure Control Valves

A pressure control valve helps in maintaining a set pressure in the hydraulic system. Pressure control valves are used mainly in industries where keeping system pressure below a desired upper limit is crucial such as oil and gas industries. 

There are types of pressure control valves:

  • Relief valves
  • Constant pressure reducing valves
  • Sequence valves
  • Counterbalance valves
  • Over center valves
  • Unloading valves

Flow Control Valves

Flow control valves regulate the flow rate at the throttling point by increasing or decreasing the opening of a hydraulic circuit. The flow rate helps in determining the rate of energy transfer at any given pressure. 

There are five most common types of flow control valves:

Different Types Of Hydraulic Valves

Hydraulic valves direct any type of flow of liquid medium through a hydraulic system and control the flowing fluid. There are different systems utilized in hydraulic to enable this to happen. Valves can be precisely worked (by handle, handle or cam), electric solenoid-worked, or pilot-worked (air or water powered weight incites the valve). A few valves utilize the weight of the circuit’s liquid to activate themselves, as with alleviation valves. Valves can likewise be incited with links, switches, plungers, torque engines, etc. There are many industrial valves supplier in the market which provides different types of valve for various purpose in which the most common valve the use water valve. Here some other valves which we supply to our clients.

Hydraulic Pressure Reducing Valve

Hydraulic pressure valve exerts its pressure by the hydraulic fluid in all the direction and exerts the force per unit area. Thus hydraulic pressure is used in various hydraulic systems like jaws of life, metal shears, automobile brakes, car crusher etc.

Butterfly Valve

A valve comprising of a pivoting round plate or a couple of pivoted half-circle plates appended to a transverse shaft and mounted inside a pipe so as to manage or forestall stream. Butterfly valves work comparatively to ball valves. Pivoting (rotating) the handle, either physically or with a pneumatic framework, turns the plate opposite or parallel to the stream of the liquid.

Hydraulic and Pneumatic Valve

A solenoid valve is an electrically enacted valve, regularly used to control the stream or heading of air or fluid in liquid power frameworks. Solenoid valves are utilized in both hydraulic pressure and pneumatic pressure power system, and regularly in either poppet or spool arrangements.

Check Valve

A check valve, non-return valve, reflux valve, maintenance valve or single direction valve is a valve that ordinarily permits liquid (fluid or gas) to course through it in just a single bearing.

Globe valve

It has a unique relation to ball valve, is a sort of valve utilized for controlling stream in a pipeline, comprising of a portable plate type component and a stationary ring seat in a for the most part round body. These globe valves are generally used in the petroleum industry.

Ball valve

A ball valve is a type of quarter-turn valve which utilizes an empty, punctured and rotating ball to control move through it. It is open when the ball’s gap is in accordance with the stream and shut when it is turned 90-degrees by the valve handle. The handle lies level in arrangement with the stream when open, and is opposite to it when shut, making for simple visual affirmation of the valve’s status.

Ball valves are solid, performing great after numerous cycles, and dependable, shutting safely even after extensive stretches of neglect. These characteristics settle on them a brilliant decision for shut off and control applications, where they are frequently linked to doors and globe valves, yet they come up short on their fine control in throttling application.
