Automatic Air Vent Valves
Automatic air vent valves can discharge the air that formed into the hydraulic circuits of the heating/cooling or sanitary systems. This avoids the onset of negative phenomenon, that could compromise the lifetime and the efficiency of the thermal system. The automatic air vent valves are performing either during the initial phases of the system load where the air quantity to be discharged is high, or during the operation where the discharge shall not happen continuously but intermittently, with modest air amounts to be discharged in a progressive way.
The components of the discharge mechanism are made by using performing and reliable materials, with particular attention to the maintenance of the mechanical features in time. The o-rings are made of EPDM. The internal spring of the obturator is made of stainless steel. The internal float is in PP-H.
