PARKER CPOM3AA11

Parker CPOM3AA11 Pilot-Operated Check Valve

Description

This is a Parker CPOM3AA11, a pilot-to-open check valve designed for hydraulic systems requiring secure load-holding capabilities. As a sandwich plate valve, it is designed to be mounted between a directional control valve and its subplate, conforming to NG10 / CETOP 5 standards. The valve allows free flow in one direction and blocks it in the reverse direction until a pilot pressure signal is applied to open the check. It is rated for a maximum operating pressure of 350 bar.
