High Performance Flange Butterfly Valve

Waits is able to produce and provide high performance flange butterfly valve. We are a large valve manufacturer with our own production base. We were first established in the United States in 1994 and set up a Chinese branch in 2008. This butterfly valve adopts an innovative double eccentric structure design, with excellent performance, long service life, high cost performance, and is widely used in the air separation system of petrochemical projects.

Product Description

Double eccentric structure design
When the valve is opened, the eccentric valve disc will quickly leave the valve seat sealing surface, so the contact time between the valve disc and the valve seat sealing surface is short. This design can extend the service life of the valve.
