PVC worm-geared butterfly valves are compact, lightweight, and efficient, making them a popular choice for various piping systems. They feature a simple design, minimal material usage, and rapid 90° rotational operation with low torque requirements. These valves excel at cutting, connecting, and regulating flow within pipelines, delivering reliable sealing and precise fluid control.

The worm gear, developed by Sanking, is constructed entirely from plastic, setting it apart from traditional metal gears. This design enhances corrosion resistance, extends lifespan, and reduces weight. Additionally, the multi-speed gearbox further minimizes switching torque. The valve includes an ISO 5211 installation platform, enabling seamless integration with standardized electric actuators without the need for extra adaptors. Sanking offers PVC worm-geared butterfly valves in sizes ranging from 1-1/2" to 12" and also provides options in CPVC, PPH, and PVDF materials.
