Features

Fastest in-line repair - Repairable in line more easily and at less cost than other similar valve. Stem, disc, and packing can be quickly removed through the yoke, and the seat fully exposed for "like new" restoration.
High dependability - One-piece forged body without pressure welds, seal welds, pressure-containing threads or gaskets, body/bonnet joints, or any of their related problems.
Greater durability - Solid Stellite® disc and seat ring all but eliminates cracking. Extra thickness of the seat ring also provides enough material to renew the seating surface over and over again.
High flow capacity - Generous port sizes and disc retraction well beyond that required for optimum flow. These features help to minimize flow velocities, and therefore, decrease the erosive forces, which shorten the life of the seat and disc.
Available off-the-shelf - An in-depth stocking program makes Welbond® valves available to you directly off-theshelf (socketweld ends standard to NPS 2½).
Convertible feature - The complete premachining of each valve body means one of the backseat designs can be converted to the other, simply by reassembly with alternate backseat bushing.
