Pneumatic Actuated Plug Valve

Pneumatic actuated plug valves use an air-powered rotary actuator to turn a cylindrical or tapered plug, providing automated shutoff and flow diversion. They are used in chemical processing, refining and industrial fluid-transfer systems.

Reliable flow isolation and automated control are essential in industrial pipelines that handle liquids, gases, and compatible process fluids. Valves Only Canada is a Pneumatic Actuated Plug Valve Manufacturer in Canada for industrial facilities requiring dependable shut-off, responsive operation, and integration with automated control systems. These valves combine a plug valve with a pneumatic actuator powered by compressed air. The actuator rotates the plug to open, close, or regulate the flow passage, depending on the valve design. Body materials, plug construction, sealing arrangements, and actuator configurations are selected according to operating pressure, temperature, media compatibility, and process requirements.

Features 

  • Compressed-air-powered actuator for automated valve operation. 
  • Quarter-turn operation for rapid opening and closing. 
  • Plug designs available in lubricated, non-lubricated, and sleeved configurations, depending on the model. 
  • Double-acting or spring-return actuator options, where available. 
  • Reliable shut-off with suitable plug and sealing materials. 
  • On/off or modulating control with compatible actuators and accessories. 
  • Remote operation through compatible PLC and DCS systems. 
  • Flanged, threaded, or other end connections, depending on valve design. 
  • Body and plug materials selected for corrosion resistance and process media compatibility. 
  • Suitable for compatible liquids, gases, and industrial process fluids.
