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 setpoint controller, signaled to control valve for the lubrication system or monitor. Open the valve and then the big (or small off), so the system ends of tubing pressure decreases pressure switch cheap, reach 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 pressure switch, the main channel A unloading. Once the two main conduits pressure reaches the set value, the piston spring force to overcome the left chamber pressure switch price move left and push the limit switch, the contacts 1 and 2 closed, pressure switches cheap, Shandong differential pressure switch, Li gifted Litas established by Changzhou gifted Litas Electrical Co., Ltd.
