Butterfly valves are quarter-turn flow control devices used to regulate, isolate, or start/stop the flow of liquids, gases, and slurries in industrial piping systems. Designed with a rotating disc positioned at the center of the pipe, these valves offer quick operation, compact structure, and lightweight construction. Butterfly valves are widely used in water treatment plants, HVAC systems, chemical industries, oil & gas, and food processing due to their reliability and cost-effectiveness. They are available in various materials such as stainless steel, cast iron, PVC, and aluminum, making them suitable for both low-pressure and high-pressure applications.
A Butterfly Valve is a quarter-turn valve that uses a circular disc (called a butterfly) to control fluid flow. When the disc is rotated by 90 degrees, the valve opens or closes, enabling quick and efficient flow control. Due to their compact size and simple design, butterfly valves are ideal for large-volume or low-pressure applications.
A butterfly valve operates through the rotation of a disc inside the valve body:
This quick quarter-turn motion makes butterfly valves efficient for frequent operation and flow regulation.
1. Wafer-Type Butterfly Valves: Used for sealing against bi-directional pressure.
2. Lug-Type Butterfly Valves: Feature threaded lugs for easy installation or removal of pipelines.
3. Double Offset (High-Performance) Butterfly Valves: Reduced friction; suitable for high-pressure systems.
4. Triple Offset Butterfly Valves: Provide tight metal-to-metal sealing for critical applications.
5. Manual Butterfly Valves: Operated by a handle or gear.
6. Actuated Butterfly Valves: Electric or pneumatic actuators for automated control.
