This valve has been realised for use on cylinders for reversible plough to obtain the automatic oil backflow and therefore the motion 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
compensated 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.
