ROSS Controls 2778C5904 is a 27 Series Pilot Operated Check Valve designed for load holding and cylinder-position retention in pneumatic systems, with a 3/4-inch port. This inline-mounted, solenoid-pilot version (24 VDC micro coil) is a 2-way, 2-position valve that uses pilot pressure to control the flow path and prevent backflow when not commanded. The model employs a poppet valve design and is intended for safety-critical applications where controlled hold and release are required in load-holding circuits.
