Introduction
Scope of the Manual
This manual provides instructions for installation,
maintenance and parts ordering for the Max-Flo Series.
Product Description
Max-Flo Series are float and thermostatic steam
traps. Float actuates the valve via a hinged lever
and linkage. Air vent is balanced-pressure design
with stainless steel welded encapsulated bellows
capable of discharging air and non-condensable gases
continuously for heavy load process.. Trap is cast iron
bodied suitable for pressures to 175 psi / 12.1 bar with
NPT connection.
WARNING
Principle of Operation
On 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.
Installation
Personal injury, property damage,
equipment damage or leakage due
to escaping steam or bursting of
pressure containing parts may result
if this equipment is over pressured or
is installed where service conditions
could exceed the limits given in the
