Z41H flange gate valveProduct Overview:

Gate valves with high and medium pressure flange connections are suitable for nominal pressurePN1.6～16.0MPa,Operating Temperature≤-29℃～550℃Cut off or connect pipeline media on various systems of petroleum, chemical, hydraulic, and thermal power plants. Applicable media include water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc. The operation modes include manual, gear transmission, electric, pneumatic, etc.

structural characteristics
1The selection of materials is meticulous, in compliance with relevant domestic and international standards, and the overall quality of the materials is high.
2Meet the requirements of advanced domestic and international standards, with reliable sealing, excellent performance, and beautiful appearance.
3The sealing pair is advanced and reasonable, and the sealing surfaces of the gate and valve seat are made of different hardness Sitaili（Stellite）Made of cobalt based hard alloy by welding, it has reliable sealing, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, and long service life.
4The valve stem has undergone quenching and surface nitriding treatment, exhibiting excellent corrosion resistance, abrasion resistance, and wear resistance.
5Adopting a wedge-shaped elastic gate structure, with thrust bearings installed on the medium to large diameter, low friction, and equipped with an impact handwheel for easy and smooth opening and closing.
6Various piping flange standards and flange sealing surface forms can be adopted to meet various engineering needs and user requirements.
