Several Issues To Pay Attention To When Purchasing Stainless Steel Gate Valves
Stainless Globe Valve Use stainless steel sealing surface components to replace the cladding carbide sealing surface of ordinary gate valves. Because stainless steel gate valves have the characteristics of wear resistance, corrosion resistance and high temperature resistance, stainless steel gate valves have been widely used in the fields of power, chemical industry, etc., and have attracted much attention. However, many consumers often do not know how to choose stainless steel gate valves, and they are very troubled. So how to choose stainless steel gate valves?
There are many types of stainless steel gate valves. When purchasing, you should combine your own working conditions and conveying fluid media. The specific precautions are as follows:
1. Look at the general standards of valves, such as valve specifications and categories, mainly including valve nominal diameter, nominal pressure, and temperature requirements;
2. The choice of stainless steel gate valve material. Choose the material that suits you according to the working conditions, such as cast iron, cast steel, carbon steel, stainless steel, ceramics, etc. If the budget is limited, you can choose cast iron valves. If the budget is sufficient, it is recommended to choose stainless steel gate valves. Because the life of stainless steel gate valves can reach 10 times that of ordinary metal valves, it is cost-effective.
3. The operating mechanism of the valve; mainly manual, electric, pneumatic, manual hydraulic, electro-hydraulic, etc., this should also be selected according to your specific needs and budget. Manual is relatively cheap, and electric stainless steel gate valves are more convenient to use and can be operated automatically.
4. Check whether the manufacturer has done performance testing of the valve. The valve must undergo pressure testing before leaving the factory;
5. Check whether the internal and external corrosion protection of the stainless steel gate valve meets the requirements;
6. Discuss with the manufacturer the packaging and transportation method of the stainless steel gate valve. When the valve is transported, lightweight plugs should be installed on both sides to seal it. Large-diameter valves should also have a simple wooden frame to fix the packaging to avoid damage during transportation. Medium and small-diameter valves can be tied with straw ropes and transported in containers;
7. Read the product manual carefully to see if it is consistent with your requirements.
