Structural features:

1, the valve cavity using pressure self-tightening sealing structure, sealing performance is better

2. The sealing surface of the valve disc and seat is made of Stetstar cobalt base carbide spray welding, with good wear resistance, high temperature resistance, corrosion resistance and abrasion resistance

3, high temperature creep resistance design

4, the valve stem adopts the whole forged structure, after tempering and surface nitriding treatment, has good corrosion and abrasion resistance

5, the valve cover packing box depth is reasonable, packing with corrosion inhibitor, reliable sealing
