Many different types of control valve body, the body types of commonly used is through single seat, through two seater, tee, sleeve type, angular, diaphragm, small flow, eccentric rotation, butterfly, ball and so on.
In the specific choice, do the following considerations:
1.Temperature and pressure of medium
When the medium temperature, high pressure and great change, should the valve core and valve seat materials chosen by temperature and pressure changes in the small valve. When the temperature is more than or equal to 250 DEG C should increase the radiator.
2. Corrosion resistance: because the medium is corrosive, as far as possible to select the structure of the valve.
3. Wear resistance: when the fluid medium is containing a high concentration of abrasive particles suspension, the valve's internal material to be hard.
4. Spool shape structure: according to the selected flow characteristics and unbalanced forces and other factors.
