As a safety measure to guarantee the operator's safety and to safeguard the machine, a maximum pressure valve is installed inside the hydraulic control unit on all hydraulic presses produced by SICMI.
The maximum pressure valve has the function of regulating the maximum pressure in the hydraulic circuit.
It is used to protect the pump and the other components of the system from excessive pressure and therefore to keep the level inside the hydraulic circuit constant.
It is a normally closed valve capable of opening when a predetermined pressure is reached and discharging the flow rate necessary to keep the circuit pressurized.
In fact, in the event of a malfunction of the hydraulic circuit, this safety valve prevents an excessive quantity of oil from reaching the cylinder, thus preventing the risk of overpressure.
