Control Valve Altitude Float Operated
Application and general chracteristics :
- It prevents from overflowing from overflowing and matains a constant level in the tank to a float
- Opening and closing are very progressive (a few centimeters from the required level)
- Prefer the installation at the bottom of the tank or close to it
Working Principle
The level in the tank is low and the float switch S is fully open. The valve A is wide open and supplies the tank. The float is in intermediary position, the float switch is half closed. Consequently, the head loss increases the pressure in the upper chamber, the valve A will close. It will be completely closed soon as no flow runs out from the float swich in high position.
