Stainless steel lined PTFE flange gate valve is made of stainless steel materials such as 304 (CF8) and 316L (CF3M) as the valve shell. The internal passage of the valve is lined with PFA, PTFE, FEP and other materials to isolate the contact between the pipeline medium and the metal valve. The stainless steel metal material prevents external corrosion and rust, and prevents corrosion from both inside and outside. Stainless steel lined PTFE gate valve is usually opened by hand wheel, and the gate plate is lifted and lowered by turning the hand wheel. Electric actuators, pneumatic actuators, two-stage worm gear transmission devices, etc. can also be installed according to customer requirements.
