Recapitulation of the characteristics of air bleed valves

Air bleed valves have a brass body and a float valve system, the technopolymer

Let us run through the properties of the air bleed valves available on the catalogues of the GNALI BOCIA company. Produced from the starting premise of a brass body, their use targets the elimination of gases dissolved into the fluid of installations, which gather in heaters or in the highest spots.
Air bleed valves are placed in such a manner as to automatically discharge air from the plants; that occurs through a floating system, realized in polymer, which opens a needle valve capable of letting excessively dissolved gases flow away.
The intervention of air bleed valves makes it possible to increase the efficiency of the plant and to prevent, under extreme circumstances, that the circulation of the thermal fluid gets blocked. A concentration of bubbles inside the pipes, in fact, may occasion significant reductions in the flow capacity, whence the need to create suitable outflow tracts.
We can find air bleed valves capable of being fitted both on a threaded end and directly on heaters; in the latter instance, miniaturization enables us to nevertheless obtain optimal performances and safety for users. That is further aided by a cautious choice of materials.
