The copper valve first used the sand casting process in the manufacturing process, and it was changed to forging process in the early 1990s.In the early 21st century, China has developed into a world copper valve manufacturing center.The maximum allowable working pressure of the finger in the technical parameter of the copper valve is to refer to the work pressure at room temperature.The mechanical strength of the valve material decreases with the increase in temperature, so the valve allows the working pressure to decrease with the increase of the medium temperature.In addition, the maximum working temperature of the medium is also limited by the filler temperature resistance. Non -metallic elastic seal valves are also limited by the temperature resistance of sealing materials.
