ValVes and components for radiators Radia toRs val ves with theRmost a tic option h seRies LF RG R401H R402H R403H R415H Versions and product codesDescription The H series valves with thermostatic option are indicated in the radiator systems where it is expected the installation of thermostatic heads to control the room temperature in order to optimize the consumption. When the special worksite protection handwheel is fully closed, it is possible to exceed static pressure values of 10 bar with the system disabled. In any case, it is advised to connect the heating elements before carrying out the pressurised seal tests on the system.

ValVes and components for radiators Radia toRs val ves with theRmost a tic option h seRies Installation of thermostatic heads The R460H, R468H and R470H thermostatic head with threaded ring nut M30 x 1,5 mm, are installed directly on the valve body after removing the worksite protection handwheel. To remove the handwheel it is necessary to counterclockwise unscrew the upper cap and then release the handwheel by levering the base using a screwdriver. The worksite protection handwheel, however, allows the valve flow rate to be partialize: by turning it anticlockwise, the valve opens; turning it clockwise the valve closes. 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: R401HX004, R402HX004 Hydraulic features The data shown are obtained according to the specifications of the EN215 Standard.
