The FIRŠT valves FBV 440C are designed: for bivalent system, where energy is taken from two heating units, for storage tank system for the loading or heat stratification and for diverting application with one inlet and three outlets.
Valves are available in DN 15 – DN 25, with internal or external thread, and are rated PN 10.
■ The FIRŠT ball valves FBV 440C are valves with three outlets and one intlet.They are used in systems with two heat sources, for the storage tank loading or storage tank heat stratification.
■ Two types of connections are avaliable: internal threads (FBV 441C), external threads (FBV 442C).
