Check valve Pilot operated check
■ hydraulical operation, pilot operated, poppet type
■ Type series: ERV 8-C-600-...
■ Description
● Series ERV 8-C-600... check valves are size 8, pilot-ope-rated, two stage, high performance screw-in valves with an M34x1,5 mounting thread. This high-pressure version is designed for an operating pressure of up to 600 bar. The valves are designed on the proven pop-pet/seat principle and are therefore leak-tight in the flow direction B to A The check function can be over-ridden by applying a suitable pilot pressure at port X. In the flow direction A to B, flow can pass freely through the screw-in valves (opening pressure = 2.5 bar). All external parts of the screw-in valves are zinc-nickel plated, and are thus suitable for use in the harshest operating environments. These valves 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.
● Screw-in cartridge valve

● Two-stage principle (decompression / main opening)
● Load pressure closing cone poppet valve
● High-pressure model
● Seat tight shut-off
