COVNA, as a pneumatic actuated butterfly valve manufacturer, we specialized in manufacturing air operated butterfly valve since 2000. COVNA’s pneumatically controlled butterfly valve are used to control the flow of a media remotely, quickly and safely.

There are two type actuation modes: Spring return pneumatic actuator also called single acting pneumatic actuator: Air to open or Air to off. Double acting pneumatic actuator: Air to open and air to close

Pneumatic butterfly valve is a kind of butterfly valve with simple structure, superior performance, high temperature resistance and corrosion resistance.

Features: 

  • Compact structure, long service life, good sealing performance, easy maintenance, quick detachable and installation
  • Pneumatic and electric devices can be configured according to user requirements to meet the needs of remote control and program control
  • Small operation torque, quickly opened 90-degree rotation, good sealing performance
  • Stable performance, Widely used in various industries for both on-off and regulating service
  • Can be equipped with positioner, limit switch, hand wheel, solenoid valve etc.
  • High Torque Up To 4678Nm, high flow

In this article, we will bring you different type electric butterfly valves for your selection:
