          Third, large-diameter electric valve structure and characteristics

          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.
