Spirax Sarco Float and Thermostatic Steam Trap 510TTB

Used in steam distribution and condensate recovery systems, the Spirax Sarco 510TTB is a cast iron float and thermostatic steam trap with a flanged body configuration. The unit carries a cast instruction reading "POINT ARROW STRAIGHT DOWN," indicating a specific installation orientation required for proper operation. Both inlet and outlet ports are protected with plastic shipping caps, visible in the photos. The body shows surface oxidation consistent with prior industrial service or storage. Spirax Sarco is a leading global manufacturer of steam system equipment, and their float and thermostatic trap designs are widely used in heat exchange applications, unit heaters, and steam heating systems where continuous condensate drainage and integral air venting are required. Float and thermostatic traps of this type operate by using a stainless steel float to modulate the valve opening in response to condensate level, while a thermostatic air vent handles non-condensable gases. The flanged body construction is suited for bolted pipeline installations. Model designation 510TTB is cast into the body but does not correspond to a currently listed Spirax Sarco catalog number; buyers should verify compatibility against original system documentation. Serial number and pressure rating are not confirmed from available photos.
