Armstrong 316 1 1/2 in NPT Inverted Bucket Steam Trap, 80 PSIG PMO

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 D696928 is the Armstrong 316 in 1 1/2 in NPT, rated 80 psig maximum operating pressure.
