Spirax Sarco Float and Thermostatic Steam Trap FTI-30 1/2 In. NPT 30 PSIG PMO

Used in steam heating and process systems, the Spirax Sarco FTI-30 is a 1/2 in. NPT cast iron float and thermostatic steam trap configured for in-line horizontal installation. The FTI series uses a straight-through piping arrangement, making it a direct replacement for low-pressure bucket traps in a wide range of industrial and commercial steam applications.

The trap operates with a float valve mechanism that modulates continuously to discharge condensate at steam temperature, while a separate internal balanced-pressure stainless steel thermostatic air vent handles non-condensable gas removal. This dual-action design supports efficient condensate handling across varying load conditions, including startup air loads and back-pressure scenarios.

Nameplate data confirms stock number 66665, PMO of 30 PSIG, PMA of 200 PSIG at 450 degrees F, and TMA of 450 degrees F at 200 PSIG. The body is cast iron with stainless steel internal components including the float, valve, and air vent. Country of manufacture is USA, per the nameplate label. Date code L17 is visible on the nameplate. The outlet port is visible on the body casting with protective cap in place.

Applicable in pharmaceutical processing, food and beverage, chemical, and general industrial steam systems where continuous condensate drainage and reliable air venting are required.
