Worm gear transmission stainless steel lined PTFE flange ball valve refers to a valve that uses a turbine head handwheel to drive the gear to rotate the switch. Stainless steel 304 or 316L is selected as the valve body material, lined with anti-corrosion PTFE materials such as PFA, FEP, PTFE, etc., to isolate the corrosion of strong acid and alkali media in the pipeline. The stainless steel material of the shell can do a good job in external volatilization corrosion prevention. It is connected to the pipeline with a flange, and the normal standard model is Q341F46/FPA
