R88 Automatic air vent valve
R88 and R88I 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
