VR*-P valves are one-way check valves constructed in the subplate mounting version.

In rest conditions, the valve poppet, which is a cone on edge seal type, is kept closed by a spring with fixed setting.

The shutter opens when the pressure in the intake line “A” exceeds the set value of the spring, added to any pressure in the outlet line “B”.

Available in three sizes for flow rates up to 400 l/min and with three different cracking pressures.
