Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields. O-Rings and gaskets are the mechanical seals, or packings, used to prevent the leakage of a gas or fluids from valves.
