Pneumatic fluorine lined regulating valve

The pneumatic fluorine lined regulating valve is a bellows sealed single seat regulating valve. The part of the control valve in contact with the medium is made using high-pressure injection molding technology, lined with highly corrosive media such as hydrochloric acid, sulfuric acid, or nitric acid. Tetrafluoroethylene F46 is sealed with PTFE bellows. Fluorine lined pneumatic control valves are widely used for process control in various processes involving highly corrosive media such as acids, alkalis, volatile gases, and liquid media.

The pneumatic fluorine lined regulating valve consists of a fluorine lined valve body assembly and a linear pneumatic multi spring diaphragm actuator. Pneumatic actuators have two operating modes: forward and reverse. As the pressure of the gas source increases, the push rod extends from the membrane chamber. This is called forward operation, which works together with the valve body assembly to form a sealed form. As the pressure of the gas source increases, the push rod retracts back into the membrane chamber.

Product features of pneumatic fluorine lined regulating valve

1. Pneumatic fluorine lined regulating valves have excellent corrosion resistance: the valve body, valve core, and valve seat are all lined with 3mm thick perfluoroalkoxy liquid, which is resistant to strong corrosion.

2. The sealing performance of the regulating valve is excellent. Double seal with PTFE bellows and packing.

3. Less leakage: The valve core and seat use soft seals, and the leakage rate is much lower than the national IV standard.

4. The fluorine lined control valve has high precision. It has a small size, light weight, and uses small pneumatic and electric actuators.
