The hard seal fixed ball valve is a valve commonly used in industrial pipeline systems. It is named because its sealing pair is metal to metal (i.e. hard seal) and the ball is a fixed structure. Here are its main uses):
The danger of valve flash explosion cannot be ignored, especially when it involves flammable and explosive media, high temperature and high pressure working conditions or static sensitive environments. Once a flash explosion occurs, it may cause casualties, equipment damage or even major accidents.
Fixed ball valves are very common in many industries with medium-to-high pressure and complex working conditions. Fixed ball valves are the preferred choice for any medium-to-high pressure, large-caliber, highly corrosive or extreme temperature media transportation and control occasions. Especially in the following scenarios with high requirements for sealing, pressure resistance and wear resistance, they are widely used:
