HC-175 - Steam pressures to 175 PSIG
During startup, air and non-condensible gases
enter the trap and are automatically vented through
an accurate balanced pressure internal thermostatic air vent. As condensate enters the trap, the float
and lever mechanism is raised, lifting the valve off
the seat, discharging the condensate. Condensate will
continue to be discharged at the same rate at which it is
entering. Any air or non-condensible gas that may
accumulate will be continually and efficiently passed by
the thermostatic air vent.
OPERA TION
Installation Tip: Always install STV Test & Block Valve as part of trap station
SEE PAGE 354
Installation Tip: Add Uniflex Pipe Coupling for ease of maintenance
