Pressure relay is a hydraulic electrical conversion element that opens and closes electrical contacts using liquid pressure. When the system pressure reaches the set value of the pressure relay, an electrical signal is sent to make the electrical components (such as electromagnet, motor, time relay, electromagnetic clutch, etc.) operate, to relieve pressure and reverse the oil circuit, to realize the sequential action of the executive components, or to shut down the motor to make the system stop working and play a role of safety protection.
