FIRŠT BALL VALVES3-way brass ball valves with Clip system

FBV 230C

Valves are available in DN 20 – DN 32, with internal or external thread, union fittings and compression fittings and are rated PN 32.

■ The FIRŠT ball valves FBV 234C,237C,238C,244C are used as diverting or mixing elements for use in heating devices (heat pumps), in HVAC systems, mixing groups, solar heating systems, for sanitary and tap water installations.

■ Four types of connections are avaliable: internal threads (FBV 234C), union fittings (FBV 237C), external threads (FBV 238C), compression fittings (FBV 244C).

OPERATIONThe FIRŠT valves FBV 230C are compact 3-way brass ball valves for use in domestic heating systems, cooling systems, drinking water applications and for use in different heating devices (e.g. heat pumps).Valves are suitable for long-lasting operation because of special sealing construction. Small rotation torque of the valve minimizes of valve blocking.Valves can be equipped with series 9000 actuators which allow high regulating accuracy and easy installation with one-click CLIP system.

MAINTENANCE Valves require no maintenance. The installation of suitable strainer is recommended.

CERTIFICATESValves FIRŠT FBV 234C, 237C, 238C and 244C are suitable for use in drinking water installations. All valves are ACS certified.
