Direct Acting, Double Check Valve – RPDR 06/08/10

Direct Acting, Double Check Valve, RPDR 06/08/10

The pilot-to-open double check valve RPDR is inline mounted with two opposing, direct-acting, spring-loaded poppet valves.

In the normal position, the closing element is pressed onto the valve seat by the spring and pressure at port C or D, and blocks flow from C to A or from D to B leak free.
If a sufficiently high control pressure is introduced at port A or B, the control piston moves, lifting the closing element off the valve seat. The valve is opened and oil flows from D to B or from C to A.

See data-sheet for drawings, dimensions, model code, etc…
