A hydraulic "plough alignment and overturning" valve is a key component in the hydraulic systems of reversible ploughs. Its main function is to coordinate and control both the alignment and tilting movement of the plough, allowing the operator to turn and position it precisely at the end of each pass over the field. This valve manages the flow of hydraulic fluid to the cylinders, ensuring smooth and safe rotation of the plough. When actuated, it allows the tilt cylinder to move, facilitating the change of position of the plough and keeping its orientation aligned with the ground when reversing. This prevents the plough from becoming misaligned or stuck during operation, improving the accuracy and stability of the implement even in uneven ground conditions. The alignment and overturning valve helps reduce wear on mechanical components and optimise farming operations, providing reliable control over the plough and reducing the risk of damage during use.
