Lining Up Plough Outside Drills Overturning Valves (Patent 2013)

Use and Operation
This valve has been designed for use on two cylinders in sequence for reversible plough to obtain the automatic alignment of load and its overturning. Two different passing calibrations have been studied, depending on diameter of the cylinder, which valves will be assembled on.

Operating instructions: first cylinder B starts lining up the load. Once it got the end stroke, cylinder A starts overturning and com- plete the rotation. At this point cylinder B takes back the plough in working position.

Materials and Features

• Body: zinc-plated steel
• Internal Parts: hardened and ground steel
• Seals: BUNA N standard
• Poppet Type: any leakage

Applications
Connect C1 to the stem, C2 to the cylinder’s block A, U1 to the block and U2 to the stem of the lining up cylinder’s B; P and T to the machine inlet. Thanks to its shape, it can be in-line assembled on a hydraulic cylinder or directly fixed on the plough through the threaded hole made on the body.
