Spirax-Sarco 50932 Trap

The Spirax-Sarco 50932 is a heavy-duty FT-125-3/4" Float and Thermostatic Steam Trap designed for modulating pressures up to 125 psig. Built with a robust cast iron body and stainless steel internals, this dual-orifice steam trap is engineered for high-condensate-load applications such as unit heaters, heat exchangers, and air handling units. Its mechanical design features a stainless steel float mechanism that ensures continuous discharge of condensate at saturated steam temperatures, while the integrated balanced pressure thermostatic air vent handles large volumes of air during start-up to prevent air binding. The 3/4" NPT connections and inline piping configuration allow for straightforward installation and maintenance in tight mechanical rooms. By maintaining a reliable liquid seal, the Spirax Sarco FT-125 prevents live steam loss, optimizing thermal efficiency across the entire steam loop. This industrial steam trap is a standard-tier specification for contractors focusing on system reliability and effective condensate drainage in low-to-medium pressure steam systems.

• Continuous Condensate Discharge: The float mechanism responds immediately to condensate level changes, ensuring no backup in the heat exchanger.
• High Venting Capacity: The dedicated air vent quickly clears non-condensable gases, reducing warm-up time and preventing system corrosion.
• Field Maintenance: Internal components are accessible without removing the trap body from the piping, reducing downtime during routine inspections.
• Rugged Internal Design: Stainless steel valve heads and seats resist erosion and water hammer damage in demanding environments.

What is the maximum operating pressure for this specific model?
The Spirax-Sarco 50932 is rated for a maximum operating pressure of 125 psig, making it suitable for standard commercial and industrial steam heating applications.

Can this trap be installed in vertical piping?
F&T traps must be installed in a horizontal orientation with the float mechanism operating vertically to ensure the valve closes properly against steam.

How does this trap handle air binding?
It utilizes an internal thermostatic air vent that opens when air is present and closes when it senses the heat of steam, ensuring the trap does not become air-bound.
