The decompression valve has the task of decompressing the pressure accumulated in the hydraulic circuit and comes into operation just before the hydraulic cylinder rises, thus avoiding overloads and preventing potential damage to the machine.

When the tamping cycle is completed or when the stop command is released, the decompression valve opens, allowing the hydraulic fluid to return to the reservoir in a controlled manner. This process ensures that the hydraulic cylinder stops safely and there are no sharp or sudden movements.

Essentially, this accessory protects the hydraulic circuit of the press and is particularly recommended when working at high pressures.
