This valve is to provide driving energy saving type valve actuators required minimum pressure and flow.
Using very small pressure drop, the valve can track loading pressure,control pump pressure, consume less power, which is the flow control valve with energy saving and inlet throttle controling.At the same time, because the valve is temperature compensated, it can not effected by the oil temperature for controling flow stablily

Note:Please use a separate pipe directly back to the tank return oil, in order to reduce the back pressure
Instructions:
Instructions:
1.Exhaust position: pressure magnet vent position can be adjusted freely, direction to facilitate the discharge valve on the air.
2.Oil return pipeline: oil return pipeline as independent as possible, to avoid interference and limiting phenomena, and reduce the back pressure.
3. Manual pressure regulating screw: when the test or electrical failure, the temporary strain used, usually then return in situ
4.Exclusion of air: to achieve stable pressure, speed switching sensitive, pipeline and valve in the air completely ruled out is very important.
