Product Description

HG Direct Operated Hydraulic Pressure Control Valves

 

There are various types of valve including Sequence Valve, unloading valve and low pressure relief valves, all of which are operated by a pressure rise in the circuit, sensed either internally or remotely.

 

Low pressure relief valves can be used as low Pressure Relief Valve, but be careful to occurrence of surge pressure. 

Sequence valve(Internal Pilot-External Drain) used to control the operational sequence of two or more actuators. If primary pressure exceeds the pressure setting, effective fluid is delivered to the secondary side.

Sequence valve (External Pilot-External Drain) used for the same purpose as for the type 2. Operated by external pilot pressure irrespective of primary pressure.

Unloading valve (External Pilot-Internal Drain) used as unloading valve. If external pilot pressure exceeds the pressure setting, the pump is turned no-load by releasing all fluid to the tank.
