Pressure Control Valves
Pressure relief and pressure reducing valves

What is a Pressure Control Valve and Why do You Need it?

Every pressure control valve switches (or controls) at a predetermined pressure setting. The switching pressure is generally a variable setting on the valve itself. A change in position of the pressure control valve (i.e. open or closed) occurs either gradually (by control) or suddenly (by switch). Pressure shut-off valves and pressure sequence valves are hydraulic valves with a fixed throttle whereas relief and reducing valves are hydraulic valves with a variable throttle.

Pressure valves are hydraulic valves that gradually (control) or suddenly (switch) change in position.

The most common types of pressure control valves are the pressure relief valve and the pressure reducing valve. Pressure relief valves control the system pressure by relieving part, or all, of the flow to tank. Pressure reducing valves reduce the pressure supplied to a sub-system of a hydraulic system. Sequence valves are used to direct the flow to a secondary circuit. Unloading valves are used to direct flow to tank at pre-set system pressure.

How DTA can help save you time, effort and money on sourcing hydraulic valves.

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. Get advice and suggestions from DTA in order to select the appropriate hydraulic valve, in terms of size and function, that suits your application and your budget.
