best 140LPM pilot check valve

This double pilot operated check valve is designed to hold hydraulic cylinders and prevent them from drifting down while your directional control valve is in the neutral position. at rest the check valves remain seated, blocking flow from entering and exiting the cylinder and locking the cylinder in place.
Pilot to close check valves typical application for the cpd valve is in a regenerative circuit such as a baler or refuse compactor. the valve allows flow from the rod end of the cylinder to regenerate with pump flow to increase cylinder speed.
Mar 27, 2012 · the performance of overcenter valves are at best when mounted into the actuator, whether it is a linear (cylinder) or a rotary (hydraulic motor) actuator. however, if not, they should be connected to the actuators with rigid piping. the disparity between a pilot-operated check valve and pilot-assisted relief valve must be noted here.

  • How does a pilot valve work? reference

    How does a pilot valve work? a pilot valve in a hydraulic system acts as a pressure-control valve allowing hydraulic fluid to pass through to another valve using either a sliding or a poppet design. if there is too much pressure on hydraulic liquid, the pilot valve will open up and let liquid pass through to diminish the pressure.

  • Check valvean overview sciencedirect topics

    Check valves, figure 2.29, are two-port valves—one for fluid to enter and the other for fluid to leave.normally, the check valve closes under the action of the spring force on the left. when the fluid flows from right to left and the fluid pressure is greater than the cracking pressures, the spool moves off of its seat and opens the valve.
