Float and Thermostatic Steam Traps (F&T Traps)

The best steam trap depends on the application. F&T traps excel in applications with fluctuating loads and require continuous condensate discharge, such as heat exchangers and unit heaters. They offer modulating discharge and reliable air venting, making them a preferred choice for many industrial and process steam systems compared to thermodynamic or bimetallic alternatives.

A float trap continuously discharges condensate from a steam system at steam saturation temperature. As condensate accumulates, a float ball rises, opening a valve orifice to release the liquid while preventing live steam from escaping. This continuous modulating action makes float traps ideal for applications with variable condensate loads.

Float balls used in F&T trap assemblies are typically manufactured from 304 or 316 stainless steel for corrosion resistance and durability under high-temperature, high-pressure steam conditions. Other materials are available upon request for specialized chemical or food-grade applications requiring specific compatibility or hygiene standards.

Yes, float balls can be customized with specific threads, fittings, through tubes, magnets, and finishes to match exact system requirements. Round and oblong shapes are available in a wide range of sizes, and units can be pressure-tested to meet the operating conditions of your particular steam trap installation.

Selecting the correct float ball size depends on the trap body dimensions, required buoyancy for actuation, operating pressure, and condensate flow rate. Consulting technical specifications and working with a manufacturer offering custom sizing ensures the float provides accurate, responsive level detection within your specific trap housing.

Yes, stainless steel float balls constructed from 304ss or 316ss are well-suited for high-pressure steam applications. They are pressure-tested to meet custom specifications, providing the strength and corrosion resistance needed to perform reliably in demanding industrial steam trap environments over extended service life.
