A butterfly valve is a mechanism that regulates the flow of materials within large pipe diameters by the quarter-turn rotation of a disc. A rod feeds through the center of a disc and this rod is connected to an actuator that controls the motion of the disc.

Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow.

Generally more economical than other types of valves. Compact Design: Requires less space, simple mechanism, and lighter weight compared to other valve types. Quick Operation: Offers rapid on/off functionality, enhancing process efficiency

The butterfly valve consists of valve body, stem, disc and a sealing ring. The valve body is cylindrical, with a short structure length and a built-in disc-shaped

Types

  1. Concentric butterfly valves – this type of valve has a resilient rubber seat with a metal disc.
  2. Doubly-eccentric butterfly valves (high-performance butterfly valves or double-offset butterfly valves) – different type of materials is used for seat and disc.
  3. Triply-eccentric butterfly valves (triple-offset butterfly valves) – the seats are either laminated or solid metal seat design.
  4. Butterfly valve with actuator electric valve - An electrically actuated butterfly valve is a quarter-turn valve controlled by an electric motor. It offers fast and precise flow regulation, remote operation, and versatility for various applications.
