13 Characteristics / Ordering Code Direct operated check valves C4V allow free flow from A to. The counter direction is blocked. The C4V series are equipped with a leak-free seat type cartridge. Function The pressure arising in port A lifts the poppet from the valve seat and releases the flow to. In the counter direction, the spring and the pressure on top of the cartridge hold the poppet onto the seat and block the flow.

16 Characteristics / Ordering Code Pilot Operated Check Valve Series CPS Pilot operated check valves of the series CPS allow free flow in one direction (A to ). The counter-flow direction ( to A) is blocked. y applying pilot pressure, the poppet can be lifted from its seat against the pressure in port. Thus flow in the counterdirection is also possible. There are 1 and 2 stage poppets available with pilot ratios of 5 : 1 and 40 : 1, to suit different operating conditions. The CPS needs to be externally drained via port L.

18 Characteristics Hydraulically pilot operated check valves C4V allow free flow from A to. The counter-flow direction is blocked. When pressure is applied to control port X, the ring chamber flow from to A is released. Up to four different pilot control ratios are available (see ordering code). Function When no pressure is applied to the X-port, the flow from to A is blocked, because the pressure in 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 to A. The seat design of the SVL valve series provides leak-free separation of port A and in the closed position.
