Product Description

The double eccentric butterfly valve, often referred to as a high-performance butterfly valve, is highly regarded for its minimal maintenance demands. Its primary application extends to the drainage systems of water plants, power plants, steel manufacturing, the chemical industry, water source engineering, environmental facility construction, and various other sectors. Particularly well-suited for water pipelines, this double eccentric butterfly valve serves as both a regulation and interception tool. As a double eccentric butterfly valves supplier, we provide long-lasting double eccentric butterfly valves known for their dependability, having met the stringent ISO standards.

 

Butterfly valves are valves which control the flow with the 90°angle turning of the disc. DISAI butterfly valves are double eccentric and rubber sealing ring is kept in place by single piece retaining ring. This design ensures 100% sealing and makes it possible to change the sealing ring without special equipment and dismantling of any parts other than retaining ring.

WORKING PRINCIPLE

The eccentric principle is that the stem shaft is both deviated from the valve body center,also deviated from the seat. The double eccentricity effect allows the butterfly plate to quickly detach from the valve seat when the valve is opened, greatly eliminates unnecessary excessive
