Control valves – C221 altitude valves pilot operated- bottom-fill version – pressure sustaining function
Detail Product :
Same control valve as C201 but fitted with a preset upstream sustaining pressure function exists in top-fill or bottom-fill versions.
Applications and general characteristics :
- It prevents from overflowing and maintains a constant level in the tank thanks to the pilot and guarantees a minimum upstream pressure.
- Openings and closings are very progressive, (a few centimeters from the required level).
- This type of valve should be used when the supply pressure is much higher (1 bar) than the head of the full tank.
- Equipped with check valves, it closes automatically in case of backflow (C221C).
