Butterfly valves are lightweight, high-efficiency quarter-turn valves designed for quick on-off and flow regulation. Featuring a rotating disc (butterfly) centered in the valve body, they control fluid flow by adjusting the disc's angle—0° for full closure and 90° for full opening. With compact structure, low torque operation and reliable sealing, our butterfly valves offer easy installation and maintenance, suitable for various industrial, commercial and municipal fluid systems.Butterfly valves are lightweight, high-efficiency quarter-turn valves designed for quick on-off and flow regulation.
