DS363H double pressure welding butterfly valve

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.

Structural characteristics

1. Compact structure, small size, light weight, flexible operation, easy to use;
2. The three-dimensional eccentric multi-layer hard sealing structure is adopted, and its sealing performance is reliable and reaches zero leakage;
3. The valve has no flange, which brings great convenience and beauty to the insulation and wrapping of pipeline;
4. It has the characteristics of high temperature, high pressure, corrosion resistance and wear resistance
