Product Description

The valve is used to hydraulically lock a cylinder or component by preventing a return flow until pressure is admitted to the
pilot port.
The poppet valve unseats against a light spring to permit free flow in one direction. As flow stops, the poppet valve reseats to
prevent return flow thereby locking the load. When pilot pressure is admitted the pilot piston unseats the poppet and allows
return flow

Stainless Steel options available on request.
