The manual valve is a control component in the pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cutoff, regulation, throttling, check, diversion or overflow relief. Valves for fluid control, from the simplest shut-off valves to the most complex self-control systems, are available in a wide variety of sizes and sizes. The nominal diameter of the valve ranges from very small instrument valves up to 10m. Valves for industrial piping. The valve can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metal and radioactive fluid. The working pressure of the valve can be from 0.0013MPa to 1000MPa. From ultra-low temperature of -269 ° C to high temperature of 1430 ° C. Valve control can be used in a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, worm gear, electromagnetic, electromagnetic - hydraulic, electric - hydraulic, gas - hydraulic, spur gear, bevel gear drive, etc. It can be operated under the action of pressure, temperature or other forms of sensing signals, according to predetermined requirements, or simply turned on or off without relying on the sensing signal. The valve relies on the drive or automatic mechanism to make the opening and closing parts lift and slide. Move, swivel or swivel motion to change the size of its runner area to achieve its control function.
