Product Overview
The Parker CPOM3DDV50 (part number 1475101) is a pilot operated check valve from Parker’s CPOM series of modular sandwich valves, designed for direct mounting between a directional control valve and its subplate in accordance with ISO 4401 / CETOP 03 (NG6) interface standards. The valve functions by permitting free flow in one direction while positively blocking reverse flow until a pilot pressure signal is applied to the integral pilot piston, which unseats the poppet and allows controlled return flow. This leak-free load-holding capability makes it essential in industrial hydraulic circuits where actuators must remain locked in position against gravity or external forces during idle periods, and where controlled decompression of trapped pressure is required before reverse flow is initiated. The CPOM3DDV50 is a “DD” pilot configuration unit, meaning the pilot signal is internally supplied from port A of the directional valve, providing reliable sequencing in clamping, holding, and load-lowering circuits.
