OLEODINAMICA MARCHESINI Plough overturning valve VRAP 80/100 SS

This valve has been designed for use on cylinders for reversible ploughs to obtain the automatic oil flow reversal, and therefore the reversal of the hydraulic cylinder which rotates the plough. It has been designed to control two cylinders on ploughs with the rotation of the frame upwards. Operation: the two cylinders work in parallel. First cylinder B starts lining up the load (as it requires less pressure). Before the end of stroke, cylinder A starts the overturning. Once the dead head point (90 degrees) has passed, the cylinders A and B restart toghether taking the plough back to its working position.hese valves are supplied with exhange pressure at about 150 bar: according to your requirements, pressure setting can be modified by adjusting the pressure regulator.
