OLEODINAMICA MARCHESINI Plough overturning valve VRA 40/50 SE

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 single pilot operated check valve which provides leakage control on the cylinder head side, only whilst the rod side must be secured on the plough's mechanical stops. This valve is not recommended for ploughs which rotate the frame upwards. These valves are supplied with exchange pressure of 125 - 140 bar.
