Product Description

Butterfly valves are quarter-turn valves that regulate fluid flow by using a disc or plate located within a pipe. Double eccentric butterfly valve, also known as high-performance butterfly valve, is characterized by two offset points in the center line of the valve shaft. The main difference between the different types of butterfly valves is the arrangement of the disc and shaft.

Among them, the DN1800 PN25 eccentric butterfly valve provided by TWT is a type of double eccentric butterfly valve. It is carefully made of high-quality ductile iron and strictly adheres to and complies with strict industry standards to ensure the highest reliability and performance.

There is also a triple eccentric butterfly valve. The triple offset design introduces a third offset – the offset of the sealing element itself. This configuration eliminates frictional contact between the disc and seat during opening and closing, reducing wear and extending the service life of the valve.
