Structure and characteristics of electric flange gate valve

1. Exquisite material selection, in line with relevant domestic and foreign standards, high overall quality of materials. 2. Meet the requirements of advanced standards at home and abroad, with reliable seal, excellent performance and beautiful shape. 3. The sealing pair is advanced and reasonable, and the sealing surface of gate and seat is made of Stellite cobalt base hard alloy with different hardness. The sealing is reliable, hard, wear-resistant, high temperature resistant, corrosion resistant, abrasion resistant and long life. 4. The valve stem has good corrosion resistance, abrasion resistance and abrasion resistance. 5. Adopt wedge type elastic gate structure, set thrust bearing with medium and large bore, low friction force, and equipped with manual impact, easy to open and close. 6. Various fitting flange standards and flange sealing cover can be adopted to meet various engineering requirements and user requirements.
