Steam traps are maintenance items, internal components wear over time and need periodic replacement. AQ Process Systems sources and exports complete repair kits and individual spare parts for all major trap types and equipment brands. A repair kit restores the trap to as-new performance at a fraction of the replacement cost.
We supply replacement spare parts compatible with all major steam trap brands and models. Parts include valve and seat sets, floats (ball and bucket), bellows elements, bimetallic elements, thermodynamic discs, gaskets, and springs.
For plants with large trap populations, we offer spare parts packages covering the most common trap models in your installed base, ensuring parts availability for planned maintenance and emergency repairs.

The most common parts by trap type: thermodynamic, disc and seat (the only wear parts); inverted bucket, valve and seat, bucket (corrosion); float & thermostatic, thermostatic air vent element, ball float (leaking), valve and seat; thermostatic, bellows element or bimetallic element. All types need cover/bonnet gaskets at every opening.
Yes. AQ Process Systems parts are sourced from certified manufacturers to OEM-equivalent specifications and tolerances, providing the same performance as original manufacturer parts at competitive pricing. We cross-reference parts by equipment manufacturer, model, and type for direct replacement.
Replacement intervals depend on steam quality, pressure, cycling frequency, and the specific trap type. General guidelines: thermodynamic disc and seat, every 3-5 years; thermostatic bellows elements, every 3-5 years; inverted bucket internals, every 5-8 years; FT air vent elements, every 2-5 years. Regular trap surveys identify when replacement is needed before total failure.
Yes, most steam traps are designed for field repair. Replacing the internal components (using a repair kit) restores the trap to as-new performance at 30-50% of the cost of a new trap. The trap body, which rarely wears, is reused. Repair is recommended when the body is in good condition and the correct repair kit is available.
Yes. We analyse your installed trap population (by manufacturer, model, and type) and prepare a recommended spare parts package covering the most common repair kits and consumables. This ensures parts availability for planned shutdowns and emergency repairs, reducing downtime and expediting costs.
