The FIRŠT FBV 220C-M control valves are compact 2-ways motorised brass ball valves with characterizing inserts. Insert assures excellent control characteristics with equal percentage flow characteristics which perceftly matches the heat output characteristics of heating units.
Control valves are available in DN 15 – DN 25, with internal or external thread, union fittings and compression fittings.
FIRŠT control valves with electric actuators are used as control elements for HVAC applications (for use in heating systems, solar systems, zone heating etc.). Equal percentage flow characteristics produces excellent control characteristics and linear thermal output according to the valve opening angle.
Five types of connections are avaliable: internal threads (FBV 220CM), external threads and union fitting (FBV 221C-M), union fit. (FBV 222C-M), compression fittings (FBV 223C-M), external threads (FBV 224C-M).
