High Temperature Pressure Power Station Gate Valves

Execution standards
1. The manufacturing and acceptance technical conditions shall comply with the provisions of Japanese standard E101 and JB/T3595-93 for valves used in thermal power generation.
2. The welding groove shall be in accordance with the provisions of the power industry management standard 78DG or the size provided by the user

1. This series of valves adopts an advanced equal diameter straight through structure, which greatly reduces the flow resistance coefficient and energy loss, significantly improving the service life and performance of the valve.

2. The valve chamber adopts a pressure self tightening sealing structure with good sealing performance. The two ends of the branch pipe are welded structures.

3. The sealing surface of the gate and valve seat is made of Stellite cobalt based hard alloy welding, which has good wear resistance, high temperature resistance, corrosion resistance, and abrasion resistance.

4. The valve stem has undergone quenching and surface nitriding treatment, exhibiting excellent corrosion resistance and abrasion resistance.
