Spirax Sarco FT44 Cast Steel Ball Float Steam Trap DN80 & DN100

The Spirax Sarco FT44 is a heavy-duty cast steel ball float steam trap designed for high-capacity condensate drainage in industrial steam systems. Available in DN80 and DN100 sizes, this trap features an integral automatic air venting facility that ensures efficient removal of air and non-condensable gases during system start-up and normal operation.

Constructed with a carbon steel body conforming to PN40 design conditions, the FT44 is suitable for saturated steam service up to 32 bar g. The trap operates on the ball float principle — as condensate enters the trap body, the float rises and opens the main valve, allowing continuous condensate discharge at steam temperature without steam loss. The thermostatic air vent responds to temperature, opening when cool air or condensate is present and closing as steam approaches.

The FT44 is available with horizontal flanged connections to EN 1092 PN40, ASME Class 150/300, and JIS/KS 20K standards. Covers can be drilled and tapped (3/8" bottom or ½" top) with BSP or NPT threads for drain cock installation if required.

The Spirax Sarco FT44 ball float steam trap is engineered for medium to large steam systems requiring high condensate handling capacity. Typical applications include:

- Process heating equipment in chemical and petrochemical plants - Heat exchangers and shell-and-tube units - Large steam mains and distribution headers - Paper and pulp industry dryers - Food and beverage processing plants - Textile manufacturing steam systems - Pharmaceutical production facilities - Power generation auxiliary systems

The trap is particularly suited for applications where continuous, modulating condensate discharge is required without water-logging or steam loss.
