guangzhou atech valve co

The opening and closing parts of the imported stainless steel flange gate valve are gate plates. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, but cannot be adjusted or throttled. The gate has two sealing surfaces. The most commonly used mode is that the two sealing surfaces of the gate valve form a wedge shape. The wedge angle varies with the valve parameters. Imported<

. Flange gate valve driving mode classification: imported manual gate valve, imported pneumatic gate valve, imported electric gate valve. Gate valve materials include: cast iron gate valve, imported ductile iron gate valve, imported stainless steel gate valve, imported forged steel gate valve, etc.

The applicable media of stainless steel gate valve are: water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc.<
Stainless steel gate valve its other The main features are as follows:<
, The materials are carefully selected and meet the relevant German standards, and the overall quality of the materials is high.<
, In line with the requirements of Lake's advanced standards, the sealing is reliable, the performance is excellent, and the appearance is beautiful.<
, The sealing The pairing is advanced and reasonable. The sealing surfaces of the gate plate and valve seat are made of Stellite (
) cobalt-based carbide surfacing with different hardnesses. The sealing is reliable, high hardness, wear-resistant, high-temperature resistant, and corrosion-resistant. It has good scratch resistance and long service life.<
The valve stem has been tempered and surface nitrided to have good corrosion resistance, scratch resistance and wear resistance.<
It adopts wedge type The large-diameter thrust bearing in the elastic gate structure has low friction and is equipped with an impact handwheel for easy opening and closing.<
Various piping flange standards and flange sealing surface forms can be used to meet various engineering needs and User request.
