List of featured suppliers of BUTTERFLY VALVES on Building Products Index
Butterfly valves are mechanical devices used to regulate the flow of fluids in a pipe or duct. They are composed of a circular disc that pivots around a central axis, which can be controlled by a handle or actuator. When the valve is opened, the disc rotates to allow fluid to pass through, and when it is closed, the disc seals against the valve body to prevent flow. Butterfly valves are commonly used in HVAC systems, water treatment plants, and other industrial applications where precise flow control is required.
