Product introduction
The high and medium pressure flange gate valve is suitable for cutting off or connecting the pipeline medium on the various system pipelines of petroleum, chemical, hydraulic and thermal power stations with nominal pressure PN16-16.0MPa and working temperature ≤-29°C~550°C. Applicable medium: water, oil, steam, and acid, alkali, ammonia, urea, sulfur-containing natural gas, etc. Modeling methods are: manual, gear transmission, electric, pneumatic and so on.
Electric gate valve structure and characteristics
1. Selection of materials, in line with relevant domestic and international standards, high overall quality of materials.
2. It meets the requirements of advanced standards at home and abroad, with reliable sealing, excellent performance and beautiful appearance.
3. The sealing pair is advanced and reasonable. The sealing surfaces of the ram and the valve seat are made of Stelita with different hardness. The drill-based hard alloy is surfacing, reliable sealing, high hardness, wear resistance, high temperature resistance and resistance. Corrosion, anti-cracking performance, long life.
4. The valve stem is tempered and surface oxidized, and has good corrosion resistance, scratch resistance and wear resistance.
5. The use of wedge-type elastic ram structure, medium and large caliber thrust bearing, small friction, and equipped with impact manual, easy to open and close.
6. Various pipe flange standards and flange sealing surface forms can be used to meet various engineering needs and user requirements.
7. It is equipped with DZW series multi-turn electric device, which has small casing, light weight and full function. The well can be used with remote computer, and electric device can be selected according to user requirements.
