Description of Stainless Steel  Gate Valve:

ZECO stainless steel gate valve is basically used for pipelines with corrosive media. For any kind of stainless steel material, the ability to resist medium corrosion is relatively limited, and is affected by many external factors, such as temperature, pressure, PH. However, as long as the heat treatment and processing process are completely in accordance with the standard in the manufacturing process, the material can be guaranteed to withstand corrosion within the range of corrosion. So in the selection of stainless steel gate valve, we need to consider the concentration of medium, working environment temperature and the selection of materials and other factors on corrosion resistance. ZECO is a professional manufacturer of stainless steel gate valves for nearly 30 years, providing professional suggestions for users to choose models and materials for working conditions.
