This family represents the evolution of the “Giacomini Programma 80” that, with its functional innovative characteristics (the thermostatic element and the pipe union with self-sealing element in plastic material) imposed itself on the market from 1979 on. Today the “Giacotech” TG, F series is presented in an updated and extended form both for completeness of the range and in the technical aspects. The current series offers a more complete range of products, from micrometric valves with thermostatic option to simple valves with thermostatic option, from manual valves to lockshields, all provided in both the iron and the adapter versions. In this way the installer is able to choose with the confidence to identify and use the most suitable for his needs. Among the peculiar characteristics of the “Giacotech” TG, F series, in particular:

• the introduction of a self-sealing element made of elastomeric material instead of plastic material;
• the unification of the adapter bases for the most used sizes;
• the restyling of the handwheels of the thermostatic micrometric valves;
• the introduction of worksite protections to preserve the thermostatic connection from accidental damage during installation.

Radiator valves - TG, F series 0157EN 08/2024 THERMOSTATIC OPTION Micrometric valves with thermostatic option Micrometric valves with thermostatic option The “Giacotech” TG, F series micrometric valves with thermostatic option, are easily equipped with thermostatic heads or thermo-electric actuators, in order to allow the automatic control of the room temperature, guaranteeing comfort and energy saving. Therefore is possible to use the thermostatic heads with liquid sensor and Clip-Clap quick connection (R460, R468, R470), with remote sensor (R462), with remote sensor and knob (R463) or chronothermostat for radiators (K470H, K470W). The thermostatic heads and chronothermostat for radiators are installed directly on the valve body after removing the micrometric manual handwheel. To remove the micrometric manual handwheel proceed as follow: 1) remove the upper cap using a screwdriver; 2) remove the internal adjustment pin; 3) remove the handwheel by turning it counterclockwise; 4) remove the cam using a screwdriver. Warning. With thermostatic head installed on the valve body, to avoid excessive loads on the seal gasket of the thermostatic bonnet (with the resulting risk of jamming and locking) during the summer months, is is recommended to place the knob in the fully open position, as marked by the symbol . In case of malfunction of the bonnet it is possible to replace the stem O-Ring, by unscrewing the nut using an hexagonal wrench 11 mm. If the problem persists is also possible to replace the complete bonnet using the appropriate key R400. R400 Nut Stem Spring Gasket O-Ring Body BONNET MICROMETRIC ADJUSTMENT The “Giacotech” TG, F series micrometric valves with thermostatic option are characterized by the possibility of carrying out the micrometric adjustment through which it is possible to partialize the opening of the valve operating in manual mode (i.e. without thermostatic head mounted on them). Removing the upper cap gives access to the adjustment scale: The adjustment can be made by moving the metal pin to the position suitable for your needs, according to the specific diagrams of each individual valve.

Radiator valves - TG, F series 0157EN 08/2024 1110 Micrometric valves with thermostatic option DIMENSIONS WITH THERMOSTATIC HEADS Warning. On systems equipped with thermostatic heads, the use of the R147N pressure differential valves is recommended, in order to avoid overpressure phenomena derived from the possible closure by contemporaneousness factor of the heads.

Radiator valves - TG, F series 0157EN 08/2024 1312 THERMOSTATIC OPTION The “Giacotech” TG, F series micrometric valves with thermostatic option, are easily equipped with thermostatic heads or thermo-electric actuators, in order to allow the automatic control of the room temperature, guaranteeing comfort and energy saving. Therefore is possible to use the thermostatic heads with liquid sensor and Clip-Clap quick connection (R460, R468, R470), with remote sensor (R462), with remote sensor and knob (R463) or chronothermostat for radiators (K470H, K470W). The thermostatic heads and chronothermostat for radiators are installed directly on the valve body after removing the worksite protection handwheel. To remove the worksite protection handwheel proceed as follow: 1) unscrew the upper cap counterclockwise; 2) relase the handwheel by levering the base using a screwdriver. Warning. With thermostatic head installed on the valve body, to avoid excessive loads on the seal gasket of the thermostatic bonnet (with the resulting risk of jamming and locking) during the summer months, is is recommended to place the knob in the fully open position, as marked by the symbol . In case of malfunction of the bonnet it is possible to replace the stem O-Ring, by unscrewing the nut using an hexagonal wrench 11 mm. If the problem persists is also possible to replace the complete bonnet using the appropriate key R400. R400 Nut Stem Spring Gasket O-Ring Body BONNET WORKSITE PROTECTION HANDWHEEL The worksite protection handwheel allows to preserve the valve from accidental blows during transport and installation. Furthermore, the handwheel allows to manually partialize the valve flow rate; by rotating the upper cap counterclockwise, the valve will open, turning it clockwise the valve will close; at 36° cap rotations correspond to temperature variations of 1 °C.

Radiator valves - TG, F series 0157EN 08/2024 2322 Valves with thermostatic option and KEYMARK (EN215) certification Valves with thermostatic option and KEYMARK (EN215) certification Certification Description Nation 028 KEYMARK (EN215) European Community Manufacturer Giacomini S.p.A. Product R460 Reg.-No. 10676-20190830 Energy www.tell-online.eu TELL (Thermostatic Efficiency Label) European Community CERTIFICATIONS THERMOSTATIC OPTION The “Giacotech” TG, F series micrometric valves with thermostatic option, are easily equipped with thermostatic heads KEYMARK (EN215) certified, in order to allow the automatic control of the room temperature, guaranteeing comfort and energy saving. Therefore is possible to use the thermostatic heads with liquid sensor and Clip-Clap quick connection (R460, R468, R470). The thermostatic heads are installed directly on the valve body. Depending on whether the valve is equipped with a worksite protection handwheel or manual handwheel, proceed as follows:

• valves with worksite protection: to remove the worksite protection handwheel proceed as follow: 1) unscrew the upper cap counterclockwise; 2) relase the handwheel by levering the base using a screwdriver.
• valves with manual handwheel: to remove the micrometric manual handwheel proceed as follow: 1) remove the upper cap using a screwdriver; 2) remove the internal adjustment pin; 3) remove the handwheel by turning it counterclockwise; 4) remove the cam using a screwdriver. Warning. With thermostatic head installed on the valve body, to avoid excessive loads on the seal gasket of the thermostatic bonnet (with the resulting risk of jamming and locking) during the summer months, is is recommended to place the knob in the fully open position, as marked by the symbol . In case of malfunction of the bonnet it is possible to replace the stem O-Ring, by unscrewing the nut using an hexagonal wrench 11 mm. If the problem persists is also possible to replace the complete bonnet using the appropriate key R400. R400 Nut Stem Spring Gasket O-Ring Body BONNET The bonnet replacement with R400 key is not possible for the following valves: R421FX004, R422FX004, R401FX004, R402FX004, R421FX004, R422FX004, R401FX004, R402FX004.
