High pressure flange connecting steel gate valve is suitable for: water, oil, steam, etc. Operation method: manual, gear transmission, electrical, etc.

　　Structural characteristics of high pressure flange connected steel gate valve

　　1. High pressure flange connected steel gate valve meets the requirements of leading standards at home and abroad, with reliable sealing, excellent performance and beautiful appearance.

　　2. The sealing surface of gate valve seat is made of iron-based alloy surfacing or stalli cobalt based hard alloy surfacing, which has the characteristics of wear resistance, high temperature resistance, corrosion resistance, scratch resistance and long service life.

　　3. The stem of high pressure flange gate valve is tempered and nitrided externally, which has good corrosion resistance and scratch resistance.

　　4. The gate valve adopts wedge-shaped elastic gate structure, and the rolling bearing adopts medium and large caliber, with small friction and convenient opening and closing.

　　5. Various pipe distribution flange standards and flange cover types can be to meet various engineering requirements and user needs.
