Check Valves DERV
Description
Series DERV pilot-operated check valves lock a cylinder in any rest position.
They are intended for direct mounting in the cylinder.
Check Valves ERV
Description
ERV 8, ERV 8-600:
These pilot-operated check valves are size 8, two stage, high performance screw-in cartridges with an (ERV 8: M30x1.5 / ERV 8-600: M34x1.5) mounting thread. The conical-seat design ensures that the cartridges are leak-tight from B → A. The check function can be overridden by applying a suitable pilot pressure at port X. In the A → B direction, flow can pass freely through the valve (opening pressure = 2.5 bar). These screw-in cartridges are predominantly used in certain mobile and industrial applications to maintain the position of loaded actuators (e.g. outrigger cylinders) after the pump pressure has been disconnected.
Check Valves ERVH
Description
Plate-type, screw-in design
Series ERVH
Pilot-operated check valves prevent any flow in one direction. In the opposite direction, free flow with minimal pressure drop is possible. By applying a defined pilot pressure at X, the checked flow direction is held open as long as the pilot pressure is maintained.
Check Valves for SAE Flanged Connections, Fit Between Port and Flange, Sealing on Both SidesRVSAE 3/6DS
Description
Series RVSAE 3/6DS
Patent No. 38 34 066
These patented combination SAE check valves are centered between the shafts of the four SAE flange bolts. This results in a simple, compact assembly.

Description
Series RVSAE 3/6
Patent No. 38 34 066
These patented combination SAE check valves are centered between the shafts of the four SAE flange bolts. This results in a simple, compact assembly.
Check Valves REP…
Description
Series REP… check valves prevent any flow in one direction but the valves can be made to open by applying pressure to port X. In the opposite direction, flow is unrestricted (opening pressure approx. 2 bar).
