Features
FRESE Alpha Automatic Balancing Valve is designed and manufactured for automatic flow balancing of the heating and cooling circuits without 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 irregardless of inlet pressure fluctuation.
 
FRESE Alpha offers the following benefits:
1) Plug and play operation – Eliminates time consuimg system adjustments
2) Can be ditted adjacent to a bend or fitting in the pipre
3) Can be used even with the presence of dirt and debris without affecting accuracy
4) Flow depends only on the replaceable orifice plate
5) Valve sizing selection is quick and easy – only flow data is required
