Pressure Relay

Description

Technical spec

Pressure Relay is designed to control the pressure of the working fluid by switching intrinsically safe control circuits. Switching is carried out when the set pressure level in the hydraulic system is reached. The actuation setpoint is set at the factory in agreement with the customer. During operation, if necessary, it is possible to change the setpoint, which is produced by rotating the screw located in the center of the relay. The setpoint range is determined by the design of the device.
