The Stainless Steel Valve is produced with the generation of fluid pipeline. Human beings have used valves for nearly 4000 years. In ancient China, wooden plug valves were used in bamboo pipelines when drawing brine from salt wells to make salt. In 1800 BC, when the ancient Egyptians built large-scale water conservancy to prevent the Nile from flooding, they also used similar wooden cocks to control the distribution of water flow. These are the rudiments of valves.
The extensive application of industrial valves began after Watt invented the steam engine. At the beginning of the 20th century, valves made of cast iron, cast steel, forged steel, stainless steel, chromium molybdenum steel, brass and other materials appeared. It is applied to various industries and working conditions. Few domestic companies first introduced foreign valve production technology, and then introduced foreign production technology, which made the breakthrough of domestic valve production technology, the improvement of quality and the extension of service life.
