The VRAP DE-series double acting plough overturning valve is used on cylinders for reversible ploughs to obtain the automatic oil backflow and, therefore, the reversal of the motion of the hydraulic cylinder that makes the plough rotate. It is equipped with a double acting check valve, which guarantees greater safety and enables to put and block the cylinder in any position. The motion reversal of the piston rod is made through a differential type relief valve exactly in the dead point of the plough, generating more power and speed. It can also be assembled on heavy and unbalanced ploughs with cylinders with the following internal diameters: 40/50, 60/80, 80/100, 100/110 and 110/130 mm.
