Large-diameter Electric Gate Valve Usage：

High and medium pressure flanged gate valve for the nominal pressure PN1.6 ~ 16.0MPa, the working temperature s-29°C~550°C of petroleum, chemical, hydraulic, thermal power plant in various systems of pipeline, cut off or connected to the pipeline medium . Suitable media: water, oil, steam, and acid, alkali, ammonia, urea, sulfur and other natural gas. Mode of operation are: manual, gear transmission, electric, pneumatic and so on.

Large-diameter Electric Gate Valve Advantage：

1, Selection of sophisticated, in line with relevant standards at home and abroad, the overall high-quality materials.

2, In line with the requirements of advanced standards at home and abroad, reliable sealing, excellent performance, handsome in appearance.

3, Advanced and reasonable pairs of seal pair, gate and valve seat sealing surface with different hardness Stellite (Stellite) cobalt-based hardfacing welded together, reliable sealing, high hardness, wear resistance, high temperature resistance, corrosion resistance , Good scratch resistance, long life.

4, The stem by quenching and nitriding surface treatment, good corrosion resistance, scratch resistance and wear resistance.

5, The use of wedge-type flexible gate structure, setting large diameter thrust bearings, friction is small, and with a collision

manually, opening and closing easily.

6, Can adopt all kinds of pipe flange standard and flange sealing surface to meet various engineering needs and user requirements.
