Pneumatic PTFE-Lined Ball Valve
The PTFE-Lined Pneumatic Ball Valve is a corrosion-resistant valve designed for automated flow control in aggressive chemical environments, featuring a PTFE (polytetrafluoroethylene) lining to withstand acids, alkalis, and solvents, combined with a pneumatic actuator for rapid switching or precise regulation. Ideal for industries like chemical processing, pharmaceuticals, and wastewater treatment.
Features
- They are available in two structural types: two-piece split type and three-piece type, featuring low flow resistance, fast opening/closing speed and simple structure.
- With excellent chemical corrosion resistance, the pipe wall is flat and smooth, resulting in low friction resistance and adhesion during fluid transportation. Outstanding aging resistance and UV resistance greatly extend the normal service life compared with other piping systems.
- The various spool structures (V-type, O-type) of electric fluorine-lined ball valves can easily meet applications requiring two-position shut-off and regulation. The valve is directly connected to the actuator. The electric actuator has a built-in servo system without an additional servo amplifier. It can be controlled by inputting 4–20 mA signal and 220 VAC power supply. It features simple wiring, compact structure, low resistance, stable and reliable operation, etc.
