Armstrong 312 1/2 in SW Inverted Bucket Steam Trap, 125 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 D696188 is the Armstrong 312 in 1/2 in SW, rated 125 psig maximum operating pressure.
