VR*-I valves are one-way check valves cartridge type construction and can be used in blocks or panels. In rest conditions, the valve poppet, which is a cone on edge seal type, is kept closed by a spring with fixed setting. The poppet 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 of up to 300 l/min and with three different cracking pressures.
