SCROLL

DOUBLE ACTING PLOUGH OVERTURNING VALVES

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 is provided with a double pilot operated check valve which provides leakage control for the cylinder in any position. The reversal of the cylinder is controlled by a pressure compensated relief valve set to exactly in the dead head point of the plough, generating more power and speed. It can be assembled on heavy and unbalanced ploughs with cylinders with the following internal diameters: 40/50, 60/80, 80/100, 100/110, 110/130 mm.
