State Supply offers steam traps from Armstrong, Barnes & Jones, Hoffman Specialty, Illinois, Marsh, Mepco, Nicholson, Spirax-Sarco, Steamco, Sterling, and Watts. Steam traps discharge condensate and non-condensable gases from steam systems. The types of steam traps available are float-and-thermostatic, inverted bucket, liquid drain, radiator, thermodynamic, and thermostatic industrial. Steam traps open when condensate and gases need to be removed and close when steam is present.
