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. ... Sequence valves are used to direct the flow to a secondary circuit.

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 control valves perfectly complement our broad range of in-line mounted flow, needle and check valves. These pressure relief valves provide the adjustable pressure control and limiting functions often required in applications where pressures need to be accurately controlled, while allowing the facility to be manually set in the field.
