When wedge gate valves, globe valves and sealed butterfly valves are closed, they all rely on generating sufficient sealing surface pressure on the sealing surface of the valve to ensure sealing, and the sealing surface pressure is achieved by the operating torque of the valve. In the production process, this type of electric butterfly valves will still leak after closing.

How to prevent frostbite of pneumatic ball valve? The second method to avoid frostbite of pneumatic ball valve The common control circuit includes the first part, the first part is the sensitive element, which is usually a transmitter. It is also the equipment for measuring and adjusting process parameters. From the transmitter to the conditioning instrument is the conditioner. Confirm and measure the error value other than the fixed value, and then the final control unit pneumatic ball valve. The method of avoiding frostbite of pneumatic ball valve Three valves change the flow of fluid. When the process parameters can reach the desired value, in this system, the regulator outputs a pneumatic signal, which can directly instigate the piston to execute the structure. In this case, the action of the valve is provided with compressed air, which can increase the boring effect, Avoid freezing, and purify and filter.
