[0002] A valve is a pipeline accessory used to open and close pipelines, control the flow direction, and adjust and control the parameters of the transported medium. According to its functions, it can be divided into shut-off valves, check valves, regulating valves, etc. A valve is a control component in a fluid transportation system, with functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest stop valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous.
