Function C4V direct operated
Direct operated check valves C4V allow free flow from A to B. The counter direction is blocked. The C4V series are equipped with a leak-free seat type cartridge.

The pressure arising in port A lifts the poppet from the valve seat and releases the flow to B. In the counter direction, the spring and the pressure on top of the cartridge hold the poppet onto the seat and block the flow.

Function C4V pilot operated
Hydraulically pilot operated check valves series C4V also allow free flow from A to B, the counter-flow direction is blocked. When pressure is applied to control port X, the ring chamber flow from B to A is released. Up to four different pilot control ratios are available.

When no pressure is applied to the X-port, the flow from B to A is blocked, because the pressure in B is also in effect on top of the poppet. Pressurizing the X port relieves the area on top of the poppet to the drain port and allows flow from B to A. The seat design of the valve provides leak-free separation of port A and B in the closed position.

Hydraulically pilot operated valves with position control are available on request.
