There are many kinds of valves for regulating valves, such as straight through single seat, straight through double seat, angular, diaphragm, small flow, three way, eccentric rotation, butterfly, sleeve type, ball and so on. In the specific choice, the following consideration can be made:

It is mainly considered according to the selected flow characteristics and unbalance force.

When the fluid medium is a suspension containing high concentration of abrasive particles, the internal material of the valve should be hard.

As the medium is corrosive, choose the simple valve as far as possible.

When the temperature and pressure of the medium are high and varied, the valve with small change in temperature and pressure should be selected for the material of the valve core and the valve seat.

Flash and cavitation are produced only in liquid medium. In the actual production process, flash and cavitation will form vibration and noise, shorten the service life of valves, so we should prevent flashing and cavitation of valves when selecting valves.
