Types of Control Valves

There are many types of valve bodies for control valves, and the commonly used ones are straight-through single-seater, straight-through double-seater, angle, diaphragm, small flow, three-way, eccentric rotation, butterfly, sleeve, spherical, etc. When making a specific selection, the following considerations can be made:
1. It is mainly considered according to the selected flow characteristics and unbalanced force and other factors.
2. When the fluid medium is a suspension containing a high concentration of abrasive particles, the inner material of the valve should be hard.
3. As the medium is corrosive, try to choose a valve with a simple structure.
4. When the temperature and pressure of the medium are high and change greatly, the valve whose core and seat material are less affected by temperature and pressure should be selected.
5. Flashing and cavitation only occur in liquid media. In the actual production process, flashing and cavitation will cause vibration and noise, shortening the service life of the valve, so the valve should be prevented from flashing and cavitation when selecting the valve.
