Once again, we return to the topic of air vent valves; a valid help to eliminate the gases dissolved in the fluid that transports heat in our implants. Studies tell us that if, at the absolute pressure of 1 bar, we increase temperature from 20 °C to 80 °C , the maximum number of litres of [...]

Applying metallurgic knowledge to the threaded brass fittings teaches us how the alloys used in the creation of these products, if not treated correctly during all phases of manufacturing and even of installation, could suffer from a phenomenon known as Stress Corrosion Cracking (SCC). GNALI [...]

Beginning with the pressing of semi-finished product of considerable dimensions, derived from CW617N brass, begins GNALI BOCIA’s production chain for water manifolds. The subsequent processes are carried out in the Lumezzane facilities, by the use of latest-generation CNC (Computer Numerical [...]

Tubular electric heaters are usually resorted to inside open or pressurized water boilers or heaters, in order to get the fluid, normally water, to heat. For the sake of a better operation, their assembly should be done in a vertical position, but, especially, always submerged by the fluid to [...]
