Dual Pilot Operated Check Valve FD-POCV-DN10S-X-8-50 D

The FD-POCV-DN10S-X-8-50 D dual pilot operated check valve block is intended to protect the two sides/spaces of the piston (the underpiston (piston side) and the overpiston (rod side) ones) against uncontrolled change of the set extension. The valve is provided with two replaceable 2/2way valve cartridges. Supplying one of the cylinder spaces (sides) results in simultaneous opening of the check valve being controlled in the opposite space (side), enabling initiation of the intended movement. In addition, one of the cartridges has a connection/port (X) for opening the cylinder space (side) with an independent hydraulic control signal. Embedded Stecko connections enable direct connection of overflow valves, pressure gauges, pressure sensors or other devices compliant with the specification of the hydraulic system of the machine. The block provided with embedded tap screws WA and WB (separately for each space /side) enabling discharging rest pressure in the cylinder or its venting (deaeration).
