Product overview

Steam traps It is essential, without loss of live steam, to remove condensate and often air and other incondensable gases from steam systems. The Spirax Sarco range of steam traps allows the best choice to be made for all applications. A steam trap performance monitoring system complements the range.

1. Thermodynamic steam traps Thermodynamic steam traps combine reliability, simplicity and efficiency of operation; with just one moving part (a hardened stainless steel disc) they give a blast discharge with clean, tight shut-off. They are able to withstand: superheat, waterhammer, corrosive condensate, freezing and vibration. The TD trap is the first choice for removal of condensate from steam distribution systems. Sizes up to DN25. For pressures up to 250 bar. Body material: carbon steel, stainless steel or alloy steel. 2. Ball float steam traps Ball float steam traps are extremely versatile and work efficiently on both light and heavy condensate loads. Although compact in size, their discharge capacity is high and continuous, ensuring maximum heat transfer. These traps are the best choice for draining plant with automatic temperature control.

3. Balanced pressure thermostatic steam traps Balanced pressure thermostatic steam traps adjust automatically to varying steam pressures and have excellent air venting characteristics during plant start-up and during normal operation. They have large discharge capacities for their size and the robust design of the internals gives a good life expectancy. Sizes up to DN25. For pressures up to 32 bar. Body material: brass, cast steel or stainless steel.

4. Sealed steam traps Sealed maintenance free steam traps.

Range: balanced pressure, inverted bucket and bimetallic versions.

Sizes up to DN25. For pressures up to 45 bar. Body material: stainless steel.

An integral air vent is fitted as standard and an adjustable needle valve is available as an option to prevent steam locking.

Sizes up to DN100. For pressures up to 80 bar. Body material: cast iron, SG iron, cast steel or stainless steel.
