AUTOMATIC BALANCING VALVE

FRESE Alpha Automatic Balancing Valve is particularly designed and manufactured for automatic flow balancing of the heating and cooling circuits without requires any adjustment to the valve during commissioning. The balancing occurs by means of a flow rate cartridge, in which the differential pressure is held constant across an orifice plate. The result is a constant flow through the valve independent of inlet pressure fluctuation.
