Do you sometimes feel that ordinary valves are not easy to use? The seal is not tight enough? It is difficult to open and close? Or are you worried that it can't withstand high temperature and high pressure environment? Don't worry, today I will introduce to you a "powerful player" in the pipeline control industry-flange eccentric butterfly valve. It is not an ordinary butterfly valve, but a master with its own "eccentric" skills!

Valve Factory Workshop

Ball valve came out in the 50s of the 20th century, with the rapid development of science and technology, the continuous improvement of production technology and product structure, in just 40 years, has rapidly developed into a major valve. In the industrially developed countries of the West, the use of ball valves is increasing year by year.

The butterfly valve commonly divided in to these two general types, Concentric is sealed by the rubber, according to the rubber type it can be suitable for many substances, like water, or some chemical. But it usually used in below PN 16. Eccentric butterfly valve include the double or triple eccentric/offsets, the disc achieves a “cam-like rotation” during opening and closing, completely eliminating frictional wear. Taking the triple offset structure as an example, the valve stem axis forms a compound angle with the sealing surface, ensuring zero leakage even under high temperature and high pressure conditions.
