Butterfly Valve body

Butterfly Valve body

Butterfly Valve body

A butterfly valve is a type of quarter-turn valve that controls flow through a circular disc or vane by rotating the disc a quarter turn (90 degrees) within the valve body. It is commonly used in industrial applications for isolating or regulating flow in pipelines carrying fluids such as water, air, gas, steam, and various chemicals.


Industrial butterfly valves are used in a wide range of industries, including oil and gas, chemical processing, water treatment, power generation, HVAC (Heating, Ventilation, and Air Conditioning), and more. When selecting a butterfly valve for a specific application, factors such as pressure rating, temperature range, fluid compatibility, size, material of construction, and sealing performance should be carefully considered.


Some Common types of Industrial Butterfly Valves

  • Concentric Butterfly Valve
  • Double Offset Butterfly Valve
  • Triple Offset Butterfly Valve
  • Lug-style Butterfly Valve
  • Wafer-style Butterfly Valve
  • High-Performance Butterfly Valve

Some common industrial applications for butterfly valves

  • Water and Wastewater Treatment
  • Chemical Processing.
  • Oil and Gas
  • Power Generation
  • HVAC (Heating, Ventilation, and Air Conditioning)
  • Pulp and Paper
  • Food and Beverage
  • Mining and Minerals Processing

Advantage of Butterfly Valve Body

  • Butterfly valves have low pressure drop, which benefits the pumping system of the pipeline.
  • Butterfly valves are quick-acting and have a simple operating mechanism. There are various types of automatic actuation systems that can be utilized in operating butterfly valves.
  • Butterfly valves are more compact and have a simpler construction and lighter weight than other valve types.
  • Butterfly valves can operate at a wider range of temperatures and pressures than ball valves.
  • Soft seats can be backed with metal seats to increase their temperature and flame resistance for fire prevention applications.
  • Butterfly valves can handle large fluid flows at relatively low pressures as well as liquids containing suspended solids.

Features of Butterfly Valve Body

  • Butterfly valve has the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switch, 90 ° reciprocating rotation, small driving torque, etc.
  • It is use to cut off, connect and regulate the medium in the pipeline, with good fluid control characteristics and closing sealing performance.
  • The butterfly valve can transport mud, with the least liquid accumulated at the pipe mouth. Under low pressure, good sealing can achieve. Good regulation performance.
  • The streamlined design of butterfly plate makes the loss of fluid resistance small, which can describe as an energy-saving product.
