Butterfly Valve

Butterfly valves feature a disc mounted on a rotating shaft that turns 90 degrees to control flow. The compact, lightweight design requires minimal installation space and offers significant cost advantages over other valve types, especially in larger sizes. The disc remains in the flow stream even when fully open, but modern high-performance designs minimize pressure drop while providing excellent flow control characteristics.

Available in wafer, lug, and flanged configurations with various seating arrangements including resilient seated and metal seated designs, butterfly valves excel in applications ranging from simple on-off isolation to precise throttling control. Their quarter-turn operation allows for quick actuation, making them ideal for automation with electric or pneumatic actuators. The combination of low cost, space efficiency, and reliable performance has made butterfly valves increasingly popular across water treatment, HVAC, chemical processing, and general industrial applications.
