When fitted into the pressure line servicing a cylinder or component, this valve acts as an automatic safety check which will
sustain an external load in the event of a rupture in the line downstream of the valve. To ensure maximum protection, the valve
should be fitted as near as possible to the cylinder of component. A poppet valve, held open by a light spring, allows free flow
in both directions at normal fluid velocities. Should a rupture occur high velocity return flow by the external load overcomes the
spring and closes the valve creating a hydraulic lock. An optional orifice sized to suit the application will meter return flow and
allow controlled movement of the external load.
Stainless Steel options available on request.
