VRA SE - Plow turning valve
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 recomended for ploughs which rotate the frame upwards.
MATERIALS and FEATURES:
- Body: zinc-plated steel. Internal parts: hardened and ground steel.
- Seals: BUNA N standard.
- Load holding: guided poppet, negligible leakage.
- These valves are supplied with exchange pressure of 125-140 bar.
- Connect C1 to the cylinder’s rod side,
C2 to the head side,
P and T to the machine’s suply.
Thanks to its shape, it can beassembled in-line on the hydraulic cylinder or directly fixed onto the plough by the threaded hole in the valve body
