Product Description

The valve is used to create a hydraulic lock in cylinder or component by preventing return flow until pilot pressure is applied.
Free flow is permitted by ball valves, which unseat against light spring pressure but reset to prevent return flow. In this double
check valve, pilot pressure to unseat the return line poppet is admitted through cross-over galleries from the pressure line, thus
flow is locked in both directions until one line is positively pressurised.

Stainless Steel options available.
