Product Description

The valve is used to hydraulically lock a cylinder or component by preventing a return flow until pilot pressure is applied.
Free flow is permitted by poppet valves, which unseat against light spring pressure but reseat 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 on request.
