Application of metal seated butterfly valve in metallurgical field
In the initial use of metallurgical blast furnaces, gate valves occupies half of the country. However, as the government has increased its efforts in environmental protection construction, and the pipe diameter of the blast furnace system has gradually increased, the metal seated butterfly valve, which is light in weight, good in sealing performance, small in […]
Can cast steel gate valves and 304 stainless steel gate valves be universal?
Commonly used cast steel gate valves and 304 stainless steel gate valves are made of steel, and some customers think that stainless steel gate valves are more expensive than cast steel. Can they be universal if they have similar performance. This is not possible. The two valves cannot be used universally, because the media they […]
