Product Overview
DS363H double pressure welding butterfly valve adopts three eccentric structure. It is an ideal hard sealing butterfly valve with bubble stage seal in high temperature, high pressure and fire protection applications. Because of the welding structure, the valve and the pipeline plane achieve permanent zero leakage. The welding butterfly valve has no flange, which brings great convenience for the pipeline insulation wrapping.
