The Xylem-Hoffman Specialty 404200 Float & Thermostatic Steam Trap designed to provide proper condensate drainage and air elimination for the steam system. This trap is designed for low-pressure systems, and it is capable of functioning at a pressure of up to 15 PSI. It has a float mechanism for the removal of condensate and a thermostatic element for the expulsion of air in the system. It is widely applied to unit heaters, heat exchangers, and coils to eliminate water hammer and ensure uniform heat distribution. The FT015H model's 3/4" size can be easily installed and is suitable for energy saving, increasing the durability of the equipment.
Xylem-Hoffman Specialty 404200 Float and Thermostatic Steam Trap
The Xylem-Hoffman Specialty 404200 is a 3/4 inch NPT Float and Thermostatic Steam Trap. It is made of stainless steel and has a maximum allowable pressure of 250 psi (17.3 bar) and a maximum operating pressure of 175 psi (12.1 bar). It is 5-1/2 inches long. The trap uses a combination of a float and a thermostatic element to remove condensate from steam lines. The float rises as the condensate level in the trap increases, closing off the steam inlet. The thermostatic element opens the steam inlet when the condensate temperature falls below a certain level. This allows the trap to discharge condensate while keeping steam in the line. The Xylem-Hoffman Specialty404200 is typically used in applications where condensate drainage is critical, such as steam tracing, unit heaters, and heat exchangers.
Key features:
Combination float and thermostatic operation: Ensures efficient condensate removal and prevents steam loss.

Maximum allowable pressure of 250 psi (17.3 bar): appropriate for a variety of steam system uses.
Maximum operating pressure of 175 psi (12.1 bar): Provides ample capacity for most industrial and commercial steam traps.
5-1/2 inches long: Compact design for easy installation in tight spaces.
Integral strainer: Protects the trap from internal damage caused by debris.
Balanced thermostatic element: Provides quick response to changes in condensate temperature for optimal performance.
Easy installation and maintenance: The trap can be installed and serviced without removing it from the pipeline.
Signs of faulty Float and Thermostatic Steam Trap 404200 Xylem-Hoffman Specialty
Reduced steam flow or pressure:
If you notice a decrease in steam flow or pressure downstream of the trap, it could be a sign that the trap is not discharging condensate properly. This could be due to a blocked inlet or outlet valve, a failed thermostatic element, or a damaged float.
Water hammer or banging noises:
Water hammer occurs when condensate accumulates in the trap and then suddenly discharges, causing a pressure surge in the pipe. This can be caused by a stuck valve, a slow-acting trap, or a damaged float mechanism.
Leaking steam:
If you see steam leaking from the trap body or vent hole, it's a clear indication of a malfunction. This can be the result of a faulty valve, a fractured body, or a damaged seal.
Increased condensate discharge:
If the trap is discharging condensate continuously or at a higher rate than usual, it could be a sign that the thermostatic element is not functioning properly. This can lead to wasted steam and reduced system efficiency.
Other potential signs:
Vibrations or shaking: This could indicate a loose internal component or a blocked vent hole.
Cold pipes: If the pipes downstream of the trap are cold to the touch, it could be a sign that the trap is not discharging condensate effectively.
Frequent cycling: If the trap is cycling on and off very frequently, it could be a sign of a malfunctioning thermostatic element or a blocked valve.
Additional tips:
Check your steam traps Float and Thermostatic Steam Trap 404200 frequently for indications of damage or wear and tear.
Listen for unusual noises like banging or hissing, which could indicate a problem.
Keep track of the trap's performance and condensate discharge rate to identify any changes.
For diagnosis and repair, speak with a certified steam trap expert if you have any suspicions about a problem.
