Features & Benefits
Continuous Modulating Discharge
Float rises and falls with condensate level, modulating valve opening for smooth continuous drainage without cycling.
No Steam Hammer
Absence of snap-action closing eliminates water-hammer and associated pipe stress in long steam lines.
High Back-Pressure Tolerance
Operates with back pressure up to 80% of inlet pressure, allowing discharge into common condensate return header.
Integral Air Vent
Bimetallic or thermostatic air vent automatically releases air and non-condensable gases during start-up and operation.
Leak-Tested Float
Every float is helium leak tested before assembly to ensure no water ingress and loss of buoyancy in service.
