- As condensate enters accumulation reservoir, air returns to the system.
- Ball float rises as condensate accumulates in the reservoir.
- Float tether cable tenses as float rises.
- Linkage arm is pulled laterally by the tether cable
- Pilot air line is opened and pressurizes the piston cylinder.
- Pilot air compresses a pneumatic piston to open the discharge valve and drain condensate from the reservoir.
- Pilot air line closes and pneumatic piston retracts as float sinks.
