Air Traps for High Viscosity Condensate: TATSU2
When the condensate accumulation reaches a certain level, the floats and the coil spring lift up the float holder to open the pilot valve.
When the pilot valve opens, air from the primary side enters the pressure chamber, pushing down the piston and opening the main valve. This allows condensate and oil to be discharged. The condensate outside the float cover is discharged first then the condensate inside the cover is discharged.
When condensate has been discharged the floats fall, closing the pilot valve. When the pilot valve closes, the pressure in the pressure chamber is released to the outlet and the piston rises, closing the main valve.
In this manner, the air trap continuously discharges condensate.
