The switch direction of Yuhuan valve is clockwise or off, and counterclockwise or on.

valves are pipeline accessories used to open and close pipelines, control the flow direction, and adjust and control the parameters, temperature, pressure and flow rate of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves and regulating valves.

valves are control components in the fluid conveying system, which have the functions of cutoff, adjustment, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief, etc. The valves used in the fluid control system range from the simplest cut-off valve to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite diverse.

valves can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media. According to materials, valves can be divided into cast iron valves, cast steel valves, stainless steel valves 21, 34 and 316, chromium molybdenum steel valves, chromium molybdenum vanadium steel valves, dual-phase steel valves, plastic valves and non-standard valves.
