Capacities
Note. Capacities shown are based on discharge at saturation
temperature. When discharging sub-cooled condensate the air vent
provides extra capacity. Under start-up conditions the thermostatic air
vent will be open, and will provide additional condensate capacity to
the main valve assembly. 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.
