The mechanical valve has a sliding column structure, light weight, convenient installation and disassembly, and manual operation, stable movement, accurate and reliable positioning, special processing technology for inner hole, small friction and wear, long service life, no lubrication required.Mainly used in petroleum, petrochemical, chemical, metallurgical, electric power, water conservancy, urban construction, fire protection, machinery, coal, food and other industries.

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. For fluid control valves, the nominal diameter of the valve ranges from a very small instrument valve to a valve for industrial piping with a diameter of 10 m. The valve can be operated according to predetermined pressure under the action of pressure, temperature or other forms of sensing signals, or can be simply turned on or off without relying on the sensing signal. The valve relies on a driving or automatic mechanism to raise and lower the opening and closing member. , swivel or swivel motion, thereby changing the size of its runner area to achieve its control function.
