The switch control of the Sanitary Pneumatic Ball Valves is a top priority. This affects a series of production of sanitary valve production and transportation. The valve should be sealed and pressure tested. If the valve switch can be used normally, and there is no leakage during the pressure test, the valve is qualified. The valve is the control component of the fluid line. The body, disc and sealing surface of the valve need to meet the corresponding requirements in order to avoid corrosion. Generally speaking, the requirements for valve strength are mainly considered from the various conditions of temperature, corrosivity and pressure of the medium. When the valve is…
