Product Description

Designed to screw directly into the port of a cylinder, hydraulic motor, manifold block etc. This valves acts as an automatic safety check which will sustain an external load in the event of a rupture in the pressure line servicing the component.
The cartridge is upstream of the pressure line thus ensuring maximum protection.
A poppet valve, held open by a light spring allows free flow in both directions at normal fluid velocities. Should a failure occur, high velocity return flow caused by the external load, overcomes the spring and closes the valve creating a hydraulic lock in the cylinder or component. An optional orifice sized to suit the application will meter return flow, and allow controlled movement of the external load.
