Pneumatic plastic ball valve is one of the most demanding anti-corrosion valve types for corrosive pipeline fluids. Compared with other valves, the biggest advantage is that the valve body is light in weight, strong in corrosion resistance, easy to install and maintain, especially suitable for medium. Cleaner liquids and gases. The pneumatic plastic ball valve has small torque and fast opening and closing speed. It can be used to cut off or connect the medium. It can also be used for fluid regulation and control. It is used in general pure water and raw water, drainage and sewage, salt water and seawater, and A variety of industries such as acid and alkali and chemical solution systems.
All parts of pneumatic plastic ball valve are assembled by injection molding, and the overall leakage point is small. It is the key device for controlling the flow of corrosive medium in chemical pipelines, but it is only suitable for normal temperature and normal pressure. The general pressure should not exceed 1.0Mpa, and the working temperature is less than 150 ° C. According to the connection form, there are flange type, thread, socket and the most common double joint order. The material is divided into PPR, PVDF, PPH, CPVC, UPVC, etc., which can withstand most of the acid, alkali and salt. High concentration of corrosion.
Pneumatic plastic ball valves must not contain hard granular impurities in the medium used to prevent scratching the surface of the ball or the sealing surface, resulting in leakage or piping for pressure or overheating! If there are impurities such as impurities, fibers, and slurry in the medium, you need to use a pneumatic V-type ball valve!
