1、Product design in accordance with NB/T 47044 and ASME B16.34 standards.

2、Valve body cavity adopts pressure self-tight sealing structure (Wood seal), the higher the pressure of the valve body cavity the better the sealing performance.

3、Swing-open structure, small flow resistance.

4、The valve seat and valve sealing surface are made of cobalt-based hard alloy surfacing or plasma spray welding, which has good resistance to high temperature, abrasion and scuffing.
