Pneumatic sanitary ball valve is composed of high-precision pneumatic actuators and quick installation ball valve assembly, also known as pneumatic quick installation ball valve, all through the precision inspection process and strict quality management, the flow path through precision polishing and sterilization treatment, the use of all-inclusive F4 seal, no dead corners and easy to clean. The valve body of the pneumatic sanitary ball valve is made of stainless steel, and the inner wall of the flow path is electronically polished to keep the fluid unimpeded. The sealing surface adopts all-inclusive PTFE, which has no dead corners and ensures hygiene, and is widely used in beer engineering, food engineering, chemical engineering, pharmaceutical engineering, biological engineering and water treatment engineering.
