Differential pressure switch is the use of two pipelines in general to issue low-pressure switch electrical signals, when the series ends of tubing pressure increased (or decreased) and exceeds the controller setpoint pressure switch Price , sends a signal to the control valve for the lubrication system or monitor. Open the valve and then the big (or small off), so the system ends of the tube pressure decreases to normal operation of the system. Differential pressure switch valve and limit switch assembly on a backplane. Grease under pressure from the main channel into the pressure switch valve piston B right chamber, the main channel A unloading. Once the two main conduits pressure reaches the set value the role of micro-pressure switch, piston cavity left to overcome the spring force to move to the left and push the limit switch, the contacts 1 and 2 closed, pressure switch wholesale, Youbisheng Electromechanical (certified), Guangdong pressure switch is provided by Changzhou gifted Litas Electrical Co., Ltd. established.
