DOUBLE ACTING PLOUGH OVERTURNING VALVE WITH ALIGNMENT
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 has been designed to control two cylinders on plughs with the rotation of the frame upwards (see scheme). Operation: the two cylinders work in parallel. Fist cylinder B starts lining up the load (as it requires less pressure). Before the end of stroke, cylinder A starts the overturning. Once the dead head point (90°) has passed, the cylinders A and B restart together taking the plugh back to its working position.
Zinc-plated steel with internal parts in hardened and ground steel
Connect C1 to the rod side, C2 to the head side of the overturning cylinder A, U1 to the head side and U2 to the rod side of the aligning cylinder B. P and T to the machine’s suply. Thanks to its shape, it can be assembled in-line on the hydraulic cylinder or directly fixed onto the plough by the threaded hole in the valve body.
