With the continuous development of modern industry, the demand for valves continues to grow, like cast steel ball valve, casting steel-static ball valve and a modern petrochemical installation requires tens of thousands of valves, with a large amount of valves. Frequent opening and closing, but often because of production, the use of selection, repair is not appropriate, there will be running, dripping, missing images, resulting in flames, blasting, poisoning, hot bad things, may form a poor product quality, energy consumption progress , equipment corrosion, material consumption, environmental pollution, and even stop production. Therefore, everyone expects to obtain high quality valves.
