ROSS Controls 2778C5904 Pilot Operated Check Valve

ROSS Controls 2778C5904 is a 27 Series Pilot Operated Check Valve that provides controlled, pilot-assisted release and load holding in pneumatic circuits. Designed to hold a cylinder in position by trapping pressure when the pilot is not actuated, this valve offers reliable backflow control in industrial automation setups. The model features a 3/4 in. main port size, enabling compatibility with standard pneumatic fittings and tubing used in medium-duty applications such as clamps, fixtures, presses, and other load-holding tasks. As a pilot-operated check valve, it uses a separate pilot signal to open and permit movement or release when commanded, while maintaining the held position when the pilot is not energized. The 27 Series PO Check Valves are built for robustness in demanding environments and are suitable for safety-critical or long-cycle applications where load retention is essential. The specific 2778C5904 designation identifies the 3/4 in. port variant within this family, aligning with standard ROSS Controls product lines for reliability and compatibility with other ROSS components in pneumatic systems.
