NBR Buna Nitrile Material Solenoid Valve Repair Kit Replacement Secondary Diaphragm MD140S MD150S MD162S MD376S

The diaphragm of the electromagnetic pulse valve is an important part of the electromagnetic valve. It is a whole piece of high-quality rubber diaphragm which is installed to block the compressed air pipe or the air outlet of the valve, the rivet head and the air discharge unloading hole, and the bolt hole with fixed support around. It is the key control part of the electromagnetic pulse valve. The electromagnetic pulse valve diaphragm is composed of a special fabric and a thin layer of high-quality elastomer attached to it.

The diaphragm of the electromagnetic pulse valve is mainly used to seal the electromagnetic valve. When the electromagnetic pulse valve receives the signal of dust injection from the pulse controller, the compressed air enters the rear air chamber through the throttle hole. At this time, the pressure of the rear air chamber makes the diaphragm close to the air outlet of the valve, and the pulse valve is in the closed state. The pulse controller outputs the signal to move the armature of the pulse valve, and the air vent of the rear air chamber of the valve is opened The pressure of the rear chamber is rapidly lost, which makes the diaphragm move backward. The compressed air is injected through the outlet of the valve. The pulse valve is in the open state and the injection starts. The electrical signal output by the pulse controller disappears. The armature of the electromagnetic pilot head of the pulse valve is reset. The vent hole of the rear chamber is closed. The pressure of the rear chamber increases, which makes the diaphragm of the pulse valve close to the outlet of the valve. The pulse valve is in the closed state and the injection stops, The air volume of the injection time is controlled by the controller.
