Relief Valve

Maintain a constant pressure in the applicable Hydraulic Line. They will limit the pressure in a circuit or relief pressure peaks to avoid damage on the other system parts such as: pumps, motors, cylinders, valves, hoses etc..

Pressure Relief with remote control Activation. 

Two different Relief settings.



Pressure Reducer

Pressure Reducing Valve is an automatic control valve designed to reduce a higher inlet pressure to a lower constant outlet pressure regardless of fluctuating flow rates and/or varying inlet pressure.

The pressure regulating pilot senses downstream pressure and modulates open or closed. This varies the pressure in the upper control chamber causing the main valve to throttle thus maintaining constant delivery pressure.

When the downstream pressure falls below the pilot setting, the pilot opens, pressure in the upper control chamber decreases, and the main valve modulates open to increase downstream pressure and maintain pilot setting.Should the downstream pressure rise above the pilot setting, the pilot closes, pressure in the upper chamber increases and the main valve throttles close to decrease downstream pressure to the pilot setting.

They are indispensable when it's necessary to operate with different pressure in one-pump.
