Armstrong's 300 Series inverted bucket steam traps are forged carbon steel traps for vertical installation, available with screwed, socket weld or flanged connections. A leverage system multiplies the bucket's force to open the valve against system pressure, the free-floating mechanism has no fixed pivots to wear, and the discharge orifice sits at the top of the trap where dirt cannot collect. A water seal around the orifice prevents live steam loss.Part D718983 is the Armstrong 314 in 1 1/4 in NPT with a 3/8 in orifice.Model 314 specifications Maximum Capacity: 6,900 lb/hr (3,130 kg/hr) Maximum Allowable Pressure: 1,130 psig @ 700°F (78 bar @ 371°C) Body Material: ASTM A105 Forged Steel, Cast 316 Stainless Steel Maximum Operating Pressure: 650 psig (45 bar) Connection Type: Screwed, Socketweld, Flanged Connection Size: 1″ (25 mm) 1-1/4″ (32 mm) Manufacturer documentation: data sheet, installation and maintenance manual.
