What is the sealing principle of electric ball valve? The orientation of the sphere is fixed, and the fluid pressure cannot make it move. The valve seats are floating, and they press the ball with the help of springs or fluid quasi force to establish the sealing pressure. Therefore, the fixed ball stainless steel ball valve can plan three sealing structures according to the application requirements: front valve seat seal, rear valve seat seal, front valve seat seal and rear valve seat seal.

After the pneumatic butterfly valve is installed with two components, the service time of the internal cylinder can be extended. The main function of the limiting position switch component is to connect the wire to the control room, and people can see the feedback signal from the control room, so that the closing and opening state of the valve can be judged. If the machine has problems, it can easily determine whether the cause is the valve or the electromagnetic component, It can save a lot of time for checking components.
