Valve is a control component in the fluid delivery system, with functions such as shut-off, regulation, flow guidance, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. Valves used in fluid control systems, from the simplest ball valve to the most complex automatic control system used in a variety of valves, its varieties and specifications are quite large.
Valve is in the fluid system, used to control the direction of the fluid, pressure, flow of the device, is to make the pipeline and equipment in the medium (liquid, gas, powder) flow or stop and can control its flow of devices.
