Hydraulic Valves

Check valves also can control pressure. Almost all check valves use a spring to return the poppet. In most valves, this spring has very light force, because any spring force results in an energy loss and heat. The light springs from most suppliers require about 5 psi to …

hydraulic pressure control valve powerpoint

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 ...

Jan 30, 2019· 2. Hydraulic Pressure Control Valve The hydraulic pressure control valve plays a vital role in controlling the leakages and bursting of pipes. Pressure control valves regulate the pressure of the fluid passing through the pipe by releasing the excess pressure. These valves maintain the pressure as entered manually by the operator.

Basic Hydraulic System

Pressure control valves. Pressure control valves influence the system pressure in a specific, pre-determined manner. This is achieved by altering the throttling cross-sections with the aid of mechanical, electrical or hydraulic movements. The range includes pressure-limiting valves, pressure-reducing valves, switching valves and load-holding ...
