Differential pressure bar (x 100 = kPa)

Capacities shown above are based on condensate at saturation temperature. When discharging sub-cooled condensate the air vent provides

extra capacity. Under start-up conditions when the condensate is cold the internal thermostatic air vent will be open and provides additional

capacity to the main valve. On 4.5 bar units this will provide a minimum of 50% increased capacity above the hot condensate figures shown.

On 10 and 14 bar units this will be a minimum increase of 100% on the published capacity. The following table gives the minimum additional

cold water capacities from the air vent.
