The electromagnetic pulse valve refers to the membrane valve controlled by electromagnetic or pneumatic pilot valves, which can instantly open and close the high-pressure air source to generate pulses.
According to the angle of valve inlet and outlet and the form of air inlet, it can be divided into three types：
（a）Right-angle electromagnetic pulse valve: membrane valve whose inlet and outlet are at right angles and directly controlled by electrical signals;
（b）Straight-through electromagnetic pulse valve: the inlet and outlet of the valve body are 180 degrees, and the membrane valve is directly controlled by electrical signals;
（c）Submerged electromagnetic pulse valve: membrane valve whose valve body air inlet is submerged in air bag and directly controlled by electric signal.
