Triple Eccentric Metal to Metal Bidirectional Butterfly Valve
Triple offset metal sealed butterfly valve uses a stem through an approximate circular plate of the disc and the valve stem rotation to drive the rotation of the disc, in order to control the effect of fluid switch. Triple offset metal sealing butterfly valve uses the three eccentric structure with multi-layer metal seal or pure metal sealing ring, different sealing materials are being used according to the different temperature request from end user. The structure of valve sealing ring that was formed after machining for triple eccentric butterfly valve is oblique cone type, the purpose of which is to let the disc open in a subtle angle and seat sealing surface can be completely separated from the sealing surface of disc, thus to reduce the friction of sealing surface during the open and close.

Additional Features
- The design of renewable seat and seal ring could avoid the valve damage caused by the wear of seal ring and reduce the cost of use.
- Fully metal to metal sealing structure is different from multilayer sealing butterfly valve. Common multilayer metal sealing structure consists of the metal sheet and graphite laminated in stallation,
