Single hydraulic control check valve (high pressure)
Single hydraulic control check valve (high pressure)
Instructions for use:
Pilot-operated check valves are used to block the cylinder in one direction, with fluid flowing in one direction and blocking the fluid in the reverse direction until pressure acts. Due to the high pressure ratio and time interval locking device, vibration of the line can be avoided under heavy load.
Application:
Connect V to the pressure flow, connect C to the side of the actuator that the actuator wants to be blocked, and connect the pipeline to the pilot line.
