FT Series Float & Thermostatic Steam Trap

Brand: Watson McDaniel

FT Series steam traps are designed for operating pressures up to 75 psiG. These float and thermostatic traps are used for lower pressure HVac and light industrial process applications.

They are used on unit heaters, water heaters, pressing machines, heat exchangers and coils. For drip applications, such as draining steam mains and steam supply lines, use 3/4" FT-075 (FT73-075-13-N).

F and T traps have excellent air-handling capability, which make them a better choice than Inverted Bucket traps for most process applications. FT Series traps have a dual inlet-outlet H-Pattern connection allowing for additional flexibility in installation.
  • H-pattern design allows piping from either side of the steam trap (there are two inlet ports at top and two outlet ports at bottom)
  • F and T traps have excellent air handling capability allows air to be discharged rapidly and steam to enter the system quickly during start-up
  • Welded stainless steel thermostatic air vent resists shock from waterhammer
  • In-line repairable (all internals are attached to cover)
