WFT Series Float & Thermostatic Steam Trap

Brand: Watson McDaniel

WFT Series with parallel port connections were specifically designed for removing condensate and air from HVac and industrial process applications such as unit heaters, pressing machines, heat exchangers and coils. They contain a high-quality welded stainless steel thermostatic air vent and stainless steel mechanism.

The WFT Series are fully repairable while the trap remains in-line and are available in 3/4” thru 2" NPT connections. For drip applications, such as draining steam mains and steam supply lines, use model 3/4” WFT-125.
  • All stainless steel internals with hardened seat and wear parts
  • In-line repairability is simplified by having all internals attached to the cover
  • Welded stainless steel thermostatic air vent resists shock from waterhammer. Live orifice air vent is available for superheated applications
  • Excellent air handling capability allows air to be discharged rapidly so steam can enter the system quickly during start-up
  • F and T traps discharge condensate immediately as it is formed (no condensate will back up into the system)
