Spirax-Sarco 54749 Kit

The Spirax-Sarco 54749 Kit is a field-proven complete valve mechanism kit engineered specifically for Float and Thermostatic (F&T) steam traps. This replacement mechanism is compatible with Spirax Sarco FT-15, FT-30, FTI-15, and FTI-30 models spanning 1/2-inch to 1-inch NPT connections. Designed for high-performance condensate drainage, the 54749 mechanism utilizes a stainless steel lever and seat assembly to ensure tight shut-off against steam while providing continuous discharge of condensate. This steam trap repair kit allows for rapid in-line maintenance, enabling technicians to restore steam system efficiency without disturbing existing piping. By replacing worn internals with this precise valve mechanism, contractors can eliminate waterlogging in heat exchangers and unit heaters, ensuring optimal heat transfer and preventing water hammer. Use this kit to maintain the modulating discharge characteristics critical for process equipment sensitive to temperature fluctuations.

• Optimized Compatibility: Fits Spirax Sarco F, FT, FTI, and FA series traps in sizes 1/2", 3/4", and 1" for versatile stock management.
• Industrial Durability: Constructed with high-grade stainless steel internals to resist corrosion and erosion in high-velocity steam environments.
• High Precision Seating: Features a lever and seat operation designed for 15 PSI and 30 PSI maximum operating pressures to prevent energy-wasting steam loss.
• Easy In-Line Service: The mechanical trap internals are designed for quick removal and installation, reducing system downtime during scheduled steam audits.
• System Reliability: Restores the modulated drainage capability required for modulating temperature control valves and heat transfer packages.

• Does the 54749 kit include the float? No, this is a mech only kit. The stainless steel ball float must be purchased separately or salvaged from the existing unit if it remains buoyant.
• Which steam trap models are compatible with this mechanism? This kit is specifically designed for the FT-15 and FT-30 series, including FTI (integral) and FA (air) variants with NPT threads.
• Can this mechanism be used in 1-1/4" traps? No, the 54749 is sized for 1/2", 3/4", and 1" traps. Larger pipe sizes require a different mechanism assembly to handle the higher condensate loads.
