4. Operation
<State 1>
Condensate flows into body [1] via the condensate inlet and then float [9] moves upward due
to buoyancy. (See Fig. 3.) In this state, vent valve part of vent valve P is open and inlet valve
part of inlet valve P is closed.

<State 2>
When condensate level rises and float [9] reaches the height at which vent valve part of vent
valve P [4] closes, inlet valve part of inlet valve P [6] opens, and driving pressure enters body
[1]. Condensate inside body [1] is transferred to condensate outlet and discharged. (See Fig.
4.) When condensate is discharged, float [9] moves downward in line with water level in body
[1]. When it drops to the height at which vent valve part of vent valve P [4] opens, inlet valve
part of inlet valve P [6] is closed. Then, internal pressure is released by vent valve, returning
to the above state 1.
