Is the valve body of the electric control valve cut-off valve?
(4) medium temperature and pressure when the medium temperature, high pressure and great change, valve core and valve seat should use the material by the temperature and pressure changes in the small valve, when the temperature is less than 250 DEG C should be added when the radiator. (5) to prevent the flash and cavitation: flash and cavitation produced only in liquid medium. In the actual production process, the flash and the formation of cavitation vibration and noise, shorten the life of the valve, so the choice should be to prevent the valve valve steam and cavitation
Electric single seat control valve in the specific choice, do the following considerations: (1) disc shape of the structure mainly based on the choice of flow characteristics and considerations such as power imbalances. (2) the wear resistance when the fluid medium that contain high concentrations of abrasive particles in suspension when the valve of the internal hard materials to. (3): corrosion resistance due to corrosive media, try to choose simple valve.
No, it isn't.Electric single seat control valve body type selection: many types of control valve body, the valve type is commonly used through single seat angle and the second through two seater. The three diaphragm small flow through the eccentric rotation of the butterfly sleeve to the spherical.
