Vickers 4CT-06-A-21 Pilot Operated Check Valve

The Vickers 4CT-06-A-21 pilot operated check valve is a one-way flow control device with pilot release for industrial hydraulic systems, allowing free flow in one direction and preventing reverse flow until pilot pressure is applied. It is designed for subplate or manifold mounting (size 06 NG6 / CETOP 3) in hydraulic cylinders, power units, and industrial machinery to provide load holding and actuator locking for controlled cylinder movement. Part of the 4CT-06 series and manufactured by Vickers / Eaton Vickers, the valve configuration code is A-21 and it is compatible with hydraulic oil and other compatible industrial fluids. Common replacements include Vickers 4CS10A21 Pilot Operated Check Valve.
