The FL - Modulating Level Float Control Valve combines an air valve and non-return valve to seamlessly maintain a steady, predetermined reservoir level. Particularly applicable in systems with fluctuating demand or rapidly changing flow conditions, the valve ensures a drip-tight closed position when the water level exceeds the float-pilot location, providing reliable and efficient water level control in any conditions.
Notes:
1. Modulated operation may cause cavitation under certain conditions. Consider using DOROT S300+ 30F/ 100F anti-cavitation valve, or two valves in series.
2. To prevent backflow, a check valve (CV) can be incorporated (FL/ CV).
