Spirax-Sarco 50930 Trap

The Spirax-Sarco 50930 is a heavy-duty 3/4" FT-75 Float and Thermostatic Steam Trap engineered for demanding industrial steam systems. This cast iron steam trap is built to manage modulating steam pressures while providing continuous condensate drainage at steam temperature. With a maximum operating pressure (PMO) of 75 psi and a maximum operating temperature of 450°F, it is a standard choice for heat exchangers, unit heaters, and air heating coils where varied loads are common. The parallel pipe connections allow for simplified piping configurations, and the stainless steel internals ensure long-term durability against erosion and water hammer. An internal balanced pressure thermostatic air vent is integrated as a standard feature, preventing air binding by rapidly discharging air and non-condensable gases during startup and operation.

• Efficient Heat Transfer: The mechanical ball float mechanism modulates to discharge condensate immediately as it forms, ensuring the heat exchanger surface remains active.
• High Cold Start Capacity: The thermostatic air vent handles significant air loads at startup, allowing the system to reach operating temperature faster.
• Superior Durability: Rugged cast iron body with all-stainless steel valve mechanisms provides high resistance to corrosion and mechanical stress.
• In-Line Serviceability: Designed for convenience, the FT-75 trap internals can be inspected or replaced without breaking the pipe connections.
• Versatile Application: Ideal for systems requiring modulating temperature control valves and heavy-duty steam main drip stations.

Is the Spirax-Sarco FT-75 suitable for high back pressure?
Yes, this Float and Thermostatic trap is specifically designed to operate efficiently even against back pressure in the return line, provided the differential pressure remains within the 75 psi rating.

What is the typical condensate capacity for this model?
The FT-75 3/4" model is rated for a capacity of approximately 1,450 pounds per hour, making it suitable for moderate to high-load heat exchange equipment.

Can the internals be serviced without removing the body from the line?
Yes, one of the primary advantages for contractors is the ability to service the seat, float, and thermostatic element by removing the cover, leaving the main body in the piping.
