Bescon Valve (Balem 441) is a float level control valve, which can be operated by electrically using a solenoid valve and/or mechanically using a pilot float valve. When the valve is used with dual functions, the valve ensures more safe and perfect performance in controlling the water level in the reservoir. Even in case of the power failure, the valve works properly ensuring you a safe running. The valve has piston type actuator operated by differential pressure with internal control piping.
