R99I

Automatic air vent valve, with isolating valve

Description
R99 and R99I automatic air vent valves can discharge large air quantities, 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
