DOROT S500 AL (3W), is a Diaphragm-actuated, Rigid Seal, Y-pattern, 3-way, Altitude Pilot 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 static water pressure. The pilot allows for differential adjustments between maximum and minimum water levels.
