The vulcanized rubber-lined butterfly valve is engineered for demanding fluid control. Its core technology involves a resilient rubber liner that is permanently bonded to the valve body and disc through vulcanization. This construction creates a bubble-tight, bidirectional seal, ensuring reliable performance in high-vacuum and throttling services. The lining provides excellent corrosion resistance against various media, including water, weak acids, and oils.
Featuring a compact, U-type flange design and a pinless disc connection to eliminate leak paths, the valve is both durable and easy to install. Its versatile design supports operation via lever, gear, or actuator. These flange butterfly valves are ideally suited for a wide range of critical applications across industries such as water treatment, desalination, marine, HVAC, and power generation, offering long service life and minimal maintenance.
