PVC butterfly control valves are made of polyvinyl chloride (PVC), a durable, lightweight, strong plastic known for its fire resistance and insulating properties. These valves are favored in switching or regulating applications due to their compact structure, cost effectiveness, fast operation and large port selection. They feature a disc attached to the rod that opens when the disc rotates, allowing fluid to flow, and closes with a quarter turn of rotation perpendicular to the direction of flow. PVC butterfly valves are versatile and suitable for a variety of applications, providing reliable and efficient fluid management.
