Valve history
The valve is created with the fluid line. The use of valves by humans has been nearly 4,000 years old. In ancient China, when salt was used to absorb brine from salt wells, cork valves were used in bamboo pipes. In 1800 BC, when ancient Egyptians built large-scale water conservancy projects to prevent the flooding of the Nile, similar wooden cocks were used to control the distribution of water. These are the prototypes of the valve. The extensive use of industrial valves began after Watt invented the steam engine. At the beginning of the 20th century, valves made of various materials such as cast iron, cast steel, forged steel, stainless steel, chromium molybdenum steel, brass, etc., have appeared. Used in various industries, all kinds of working conditions. There are not many domestic companies that have introduced foreign valve production technologies. After introducing foreign production technologies, they have made breakthroughs in domestic valve production technology, improved quality, and increased longevity.
