Pneumatic PTFE-Lined Ball Valves

Pneumatic PTFE-lined ball valves combine a PTFE-lined flanged ball valve body with an AT series pneumatic quarter-turn actuator for automated shut-off, diversion, and switching service in corrosive chemical piping systems.

The PTFE lining forms a corrosion-resistant barrier between the process medium and the metal valve body, helping protect the valve from direct contact with compatible acids, alkalis, solvents, and other aggressive fluids. This makes the valve suitable for chemical processing, corrosive wastewater treatment, chemical dosing systems, and other applications where unlined metal valves may not provide sufficient corrosion resistance.

The valve is available in 2-way and 3-way body styles. The 2-way version is used for automated pipeline isolation, while 3-way versions can be supplied with L-port or T-port ball configurations for flow diversion, mixing, and pipeline switching applications.

The flanged end connection provides a stable bolted installation for industrial process pipelines. Standard configurations are available for moderate-pressure corrosive service, while higher pressure ratings may be customized according to valve size and project specifications.

Single-acting and double-acting pneumatic actuator options are available. The single-acting actuator uses air to open and spring return when the air supply is interrupted, while the double-acting actuator uses compressed air for both opening and closing. Pneumatic accessories such as solenoid valves, limit switch boxes, pneumatic positioners, FRL units, and pneumatic handwheels can be supplied according to the required control method.

Pneumatic PTFE-lined ball valves are commonly used in chemical plants, acid and alkali transfer systems, wastewater treatment, electroplating lines, chemical storage systems, and automated process skids handling corrosive fluids.
