The Armstrong 1011 Stainless Steel Inverted Bucket Steam Trap is built from ASTM A240 Grade 304L stainless steel, lasting three to four times longer than conventional traps. Maximum allowable pressure of 400 psig at 800°F (28 bar at 427°C), capacity up to 1,050 lb/hr (476 kg/hr), and maximum operating pressure of 400 psig (28 bar).
Heat-treated stainless steel valves and seats provide the same quality used in traps rated up to 900 psig. The compact form factor makes it ideal for space-constrained installations.
