Butterfly Valve

Definition

A butterfly valve is a valve constructed with a disc that rotates 90 degrees within the valve body to control the flow of fluid.

Purpose

Butterfly valves are used to regulate or isolate the flow of fluids in a pipeline. Their simple design and quick operation make them ideal for applications requiring frequent or rapid shut-off and flow control.

Examples of Use

1. Water Treatment Plants: Controlling the flow of water in treatment processes.
2. HVAC Systems: Managing the flow of air and liquids in heating, ventilation, and air conditioning systems.
3. Industrial Pipelines: Used in various industries to control the flow of chemicals, gases, and other fluids.

Related Terms

• Gate Valve: A valve that opens by lifting a barrier (gate) out of the path of the fluid.
• Ball Valve: A valve with a spherical obstruction that controls flow by rotating a ball with a bore.
• Check Valve: A valve that allows fluid to flow in one direction only, preventing backflow.

Notes

Butterfly valves are available in various materials and designs to suit different applications and fluid types. Proper installation and regular maintenance are important to ensure reliable operation and prevent leaks.
