Double Acting Plough Overturning Valves With Relief Valve

Use and Operation
This valve has been realised for use on cylinders for reversible plough to obtain the automatic oil back flow and therefore themotion reversal of the hydraulic cylinder that makes the plough rotating. It is provided with a double pilot check valve which guarantees high safety and enables to put and block the cylinder in any position.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 can be assembled on heavy and unbalanced plough with the following internal diameters: 40/50, 60/80, 80/100, 100/110, 110/130 mm.

These valves are supplied with exchange pressure at1 40 Bar: according to your requirements, pressure setting can be modified by acting on the pressure regulator.Relief valve is set at 90 Bar.
