The fully welded butterfly valve adopts a three eccentric structure. This valve is a bubble grade metal sealed butterfly valve used for high temperature, high pressure, and firefighting applications. This valve can be operated by a worm gear, pneumatic or electric actuator.
The welded butterfly valve 
adopts a welded connection, achieving permanent zero leakage between the valve and the pipeline plane without flanges, which brings great convenience to the insulation and wrapping of the pipeline.
