Plough turning valve

It is fitted on the turning cylinder of reversible ploughs and automatically reverses the oil flow and the cylinder, so the plough turns over from one side to the other.

• V0280, VRA 60/80 SE: single acting, with check valve on the cap side only; on the rod side the plough must rest on its mechanical stops. Suited to light, balanced ploughs. Reversing pressure up to 200 bar; G3/8 connections
• V0290, VRAP 60/80 DE, and V0282, VRAP 40/50 DE: double acting, with check valves on both sides, holding the cylinder in any position; also for heavy, unbalanced ploughs. Reversing pressure up to 250 bar
• Reversing pressure factory set at 140 bar and adjustable; maximum pressure 400 bar
• Connections: C1 to the cylinder rod side, C2 to the cap side, P and T to the tractor couplings

The numbers 40/50 and 60/80 refer to the cylinder each valve is meant for. Check yours before choosing.
