Single acting plough overturning valves
TYPE: VRA SE
USE: This valve is designed for use on reversible plough cylinders to achieve automatic reversal of the oil flow and therefore reversal of the hydraulic cylinder that rotates the plough. It is fitted with a check valve that provides flow control on the cylinder head side, while the rod side must be fixed on the mechanical stops of the plough.
This valve is not recommended for ploughs that rotate the frame upwards.
MATERIALS AND CHARACTERISTICS:
Body: Zinc-plated steel
Internal parts: hardened and ground steel
Seal: BUNA N standard
These valves are supplied with an exchange pressure of 120-140 Bar
APPLICATIONS: Connect C1 to the cylinder’s stem, C2 to the block, P and T to the machine inlet. Thanks to its shape, it can be in-line assembled on a hydraulic cylinder or directly fxed on the plough through the threaded hole made on the body.
