[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.
