The valve is used to open and close the pipeline, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the transmission medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc.
The valve is the control part of the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of countercurrent, stabilization, diversion or overflow. The valves used in the fluid control system, from the simplest stop valve to the various valves used in the extremely complex automatic control system, have many varieties and specifications.
The valve can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. According to the material, the valve is also divided into cast iron valve, cast steel valve, stainless steel valve (201, 304, 316, etc.), chrome molybdenum steel valve, chrome molybdenum vanadium steel valve, dual phase steel valve, plastic valve, non-standard customized valve, etc.
