What is a butterfly Valve? How it works?

With the growing mechanical Industry it is important to control the flows and pressure of fluids in the system. A valve is designed to fulfill this role. A valve is built to control or regulate the flow of fluid by opening, closing or partially obstructing the passageways. Valves are of various types performing different functions in different types of systems. One of these valves is a Butterfly valve, an On –off valve or similar to a Ball valve to control the flow of a fluid. A butterfly valve belongs to the family of quarter turn valves which when turned off completely blocks off the flow of fluid and when the valve is opened, the disc is rotated a quarter turn so that it allows flow of the fluid. These butterfly valves can be bi- directional and may be installed with flow in either direction, vertically or horizontally. These valves are small, compact and economical valves made from various high quality material like carbon steel, iron, PVC. The Butterfly valves can be categorized into 3 main types Rubber lined, Plastic lined, and metal.

Butterfly valves can be connected in different ways. Butterfly valves usually come in wafer and lug style and usually these valves are available in standard, double offset, triple offset options.

Butterfly valves can be operated manually or automatically. Manually actuated Butterfly valves are inexpensive and easy to operate. They have either hand lever or Gear box. Butterfly valves with gear box are slightly large in size. Automatic Butterfly valves use electric, pneumatic or hydraulic actuators. With the help of automatic valve flow can be controlled from remote location, Now that you have got to know the high standard gate valve – API 6A valve, it is important that you get this high standard valve from a top-notch manufacturer to enjoy the benefits of the valve in the best way possible. One such manufacturer is Camtech manufacturing company which are producing all types of valves and are durable.


Butterfly valves are widely used in Waster water and sewage industries. These valves are also used as Shut off valves in pharmaceutical, Chemical and food industries. Due to their compact nature they occupy very less space and offer much tighter sealing .Butterfly valves are used in carburetors of cars , Ships , Pneumatic systems , Firefighting device and Apparatus , Hydroelectric PowerStation.

You can also use the gate valve to regulate the flow of fluid to the plant by stopping the valve in mid-way. However, there are more reliable and efficient valves available in the market to regulate the pressureand amount of flow of raw material to the plant.

Butterfly valve has simple construction consisting of a body, seal, stem, and handle.  Butterfly valve consists of a rotating circular plate or hinged pair of semicircular plates or discs, attached to a transverse spindle and mounted inside a pipe in order to isolate or regulate flow. The valve is open or Closed when the disc is rotated a quarter turn. When the handle of quarter turn valve is turned 90 degrees it can be turned off i.e. handle should be perpendicular to the flow .When the valve is turned off basically disc is turned off so that it completely blocks the passageway to stop the flow of the fluid. Butterfly valve allows quick shut off.

While ordering these butterfly valves make sure they are ordered from a reputed high quality valve making companies like Camtech Manufacturing FZCO, Dubai, UAE. Dhananjay Choudhary is the Managing Director of Camtech Valves Dubai. Always be sure of the size and type of the butterfly valve needed for the service
