Can Changzhou electric flange butterfly valve and electric signal butterfly valve open and close automatically? The pneumatic ball valve actuator mentioned here is a power device that affects the operation of the entire pneumatic ball valve. It is also called a spring reset device in brief. This device has two installation types. The internal air can be compressed through the operation of the internal power push rod. The front lift must have this actuator to better control this part of the operation, This is why the pneumatic ball valve must have this part.
、 Let's briefly talk about the most commonly used electric rubber butterfly valve and electric hard seal butterfly valve.
1、 Electric soft seal butterfly valve (the raw material of butterfly valve here is ductile iron, rubber seal) This electric butterfly valve is often used for opening and closing of non corrosive water at normal temperature. There are two reasons for its leakage:
1. The butterfly plate is corroded. As it is a ductile iron plate, the valve plate will rust and leak after a long time.
2. The rubber valve seat is damaged, and the rubber wear resistance is poor after a long time of opening and closing, resulting in seal damage.
3. Due to the electric actuator, the field commissioning was not in place, resulting in leakage.
