1. Function Description
The Dorot Altitude Pilot Control Valve (' AL') is an automatic, pilot controlled, level control valve,
activated by the pressure of the pipeline. The main valve is controlled by a highly sensitive pilot, located
outside the tank. The pilot opens or closes the valve in response to the static pressure of the water. The
pilot allows for differential adjustments between maximum and minimum levels.
