The pinch valve can squeeze the sleeve by pneumatic, electric, manual or hydraulic driving methods to achieve the function of switching/ regulating. Pulse valve refers to a diaphragm valve controlled by a pilot valve such as solenoid or pneumatic, which can instantly open and close a high-pressure air source to generate pulses. The pulse valve is the main component of the bag dust collector and can be sprayed more than 1 million times. Pulse valve is a type of valve that relies on the delay effect of air flow through air resistance and air volume to turn the input long signal into a pulse signal. ATO Automation will introduce the different working principle and precautions of manual pinch valve and pulse solenoid valve.
