DUCTILE CAST IRON
FREE FLOAT STEAM TRAP WITH THERMOSTATIC AIR VENTING
Features
Reliable and durable steam trap with tight
shut-off for use on medium process equipment.
Models for horizontal or vertical piping
installation.
1. Self-modulating free float provides continuous,
smooth, low-velocity condensate discharge as
process loads vary.
2. Precision-ground float, constant water seal and
three-point seating design ensure a steam-tight
seal, even under no-load conditions.
3. Thermostatic capsule (X-element) with “fail open”
feature vents air automatically until
close-to-steam temperature.
4. Built-in screen with large surface area ensures
extended trouble-free operation.
5. Easy, inline access to internal parts simplifies
cleaning and reduces maintenance costs.

1. Line numbers within the graph refer to orifice numbers.
2. Differential pressure is the difference between the inlet and outlet pressure of the trap.
3. Capacities are based on continuous discharge of condensate 6 °C below saturated steam temperature.
4. Recommended safety factor: at least 1.5.
CAUTION
DO NOT use traps under conditions that exceed maximum differential pressure,
as condensate backup will occur!
