Hydraulic Pressure Control Valve

Hydraulic pressure control valve are found in virtually every hydraulic system, and they assist in a variety of functions, from keeping system pressures safely below a desired upper limit to maintaining a set pressure in part of a circuit. Types include relief, reducing, sequence, counterbalance, and unloading. All of these are normally closed valves, except for reducing valves, which are normally open. For most of these valves, a restriction is necessary to produce the required pressure control. One exception is the externally piloted unloading valve, which depends on an external signal for its actuation.

Hydraulic control valves are components used in hydraulic drive systems or hydraulic control systems to control fluid pressure, flow, and direction. The pressure control valve is called a pressure control valve, and the flow control valve is called a flow control valve. The control of the on, off and flow direction is called a directional control valve.

Any hydraulic system, no matter how simple it is, cannot lack a hydraulic valve. Therefore, hydraulic valves are the most widely used and most active parts (components) in hydraulic technology. To a large extent, whether a newly designed or operating hydraulic system can operate normally according to established requirements is depending on the performance of the various hydraulic valves and the matching of parameters.
