Armstrong B1671-8 Piston Cap Assembly V S 17-4 H900 for 313 Inverted Bucket Steam Trap

Armstrong part B1671-8: piston cap assembly v s 17-4 h900 for the Armstrong 313 inverted bucket steam trap (300 Series).

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.
