Hydraulic Valves
Different types of hydraulic valves

What is a Hydraulic valve and why do you need it?

A hydraulic valve properly directs the flow of a liquid medium, usually oil, through your hydraulic system. The direction of the oil flow is determined by the position of a spool. A hydraulic system can only function - as per requirements - by using valves. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose. The required size is determined by the maximum flow of the hydraulic system through the valve and the maximum system pressure.

Hydraulic valves are available in a variety of sizes and according to multiple International Standards. Hydraulic valves are available with many different mounting styles: e.g. mounting in pipe lines, with threaded connection as cartridge valves, subplate mounting or flanged mounting. Hydraulic valves are subdivided into three main categories: directional control valves, pressure control valves and flow control valves. All valves operate a different function in the hydraulic system.

You can use hydraulic valves to switch at a certain pressure or adjust the direction and flow of the fluid.

Different valves function in different ways. Check valves permit free flow in one direction and block flow in the opposite direction. The directional control valve is used to pass on the pressure medium (i.e. flow) in an orderly fashion to a particular direction. Pressure control valves switch (or control) at a certain pressure; the switching pressure may be adjusted on the valve. Flow control valves regulate the flow this is done by adjusting the size of the bores (orifices).


We Supply Different Types of Hydraulic Valves

Directional Control Valves

Directional control valves can control the start, stop and change in direction of flow of a pressure medium (i.e. hydraulic oil). Hydraulic valves as poppet or spool valve.

Type of directional control valves

Pressure Control Valves

Every pressure control valve switches at a predetermined pressure setting. This occurs either gradually with variable throttle (control) or suddenly with a fixed throttle (switch).

Type of pressure control valves

Proportional Control Valves

Proportional hydraulic valves are able to control the opening to flow proportionally instead of gradually, as is the case for most standard hydraulic valves. 

Type of proportional control valves

Flow Control Valves

Flow control valves manage the flow by decreasing or increasing the opening at the throttling point. This helps to determine speed of movement for the hydraulic actuators.
