Double Acting Plough Overturning Valves With Relief Valve

Use and operation:
This valve has been realized for use on cylinders for reversible plough to obtain the automatic oil back-flow and therefore the motion reversal of the hydraulic cylinder that makes the plough rotating. It is provided with a double pilot check valve and with a relief valve that enables to reduce the thrust pressure (block side) in order not to damage the mechanical locks and the plough ’s head. The motion reversal of the piston is made through a differential type relief valve exactly in the dead point of the plough, generating more power and speed. It’s ideal for assembly on heavy and unbalanced plough with the following internal diameters: 40/50, 60/80, 80/100, 100/110, 110/130 mm.
Applications:
Connect C1 to the cylinder’s stem, C2 to the block, P and T to the machine inlet. Thanks to its shape, it can be in-line assembled on a hydraulic cylinder or directly fixed on the plough through the threaded hole made on the body.
