Poppet check valve VD*-W* series

threadedin-linespring

VD*-W* valves are check valves with threaded “BSP” ports for mounting in-line on hydraulic lines. They allow the flow to pass freely in one direction, blocking it in the opposite direction. In rest conditions, the valve poppet is kept closed by a spring. 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 eight sizes for flow rates of up to 850 l/min and with five different cracking pressures.
