1000 Series Inverted Bucket Steam Traps in stainless steel typically last three to four times longer than conventional traps used in identical services. Heat-treated stainless steel valves and seats are of the same design, material and workmanship as those used in traps for pressures up to 900 psig and 62 bar and temperatures up to 900˚F and 482°C. More compact than cast iron or carbon steel equivalents, 1000 Series traps are ideal for trapping applications such as tracer lines, steam mains and heating and process applications.
