Sperry Vickers F3DGPC06DADB51 Pilot Operated Check Valve

The Sperry Vickers F3-DGPC-06-DADB51 Pilot Operated Check Valve is a load-holding, reverse-flow preventing valve for hydraulic control systems, delivering controlled actuator movement via a hydraulic pilot release. It belongs to the DGPC-06 series and is designed for industrial hydraulic applications, including hydraulic power units, machine tools, material handling equipment, hydraulic presses, and both mobile and stationary systems that require secure load retention and dependable valve control. This valve mounts on a subplate or manifold, uses hydraulic oil, and supports free flow in one direction with pilot-released reverse flow to prevent unintended actuator movement. It is intended for use with hydraulic cylinders and actuators and is compatible with OEM installations and system upgrades, making it suitable for repair, retrofit, and replacement projects. Common replacements include the DGPC-06-B-51, F3-DGPC-06-AB-51, and DGPC-06-A-51 variants from Vickers (Sperry Vickers). The product is industrial-grade and part of the Vickers line, reflecting its design designation F3 for corrosion resistance and robust hydraulic control.
