This design offers the greatest accessibility, thus is the easiest to maintain, especially when complete removal of the stem packing is desired. Because the stuffing box bushing is not fastened to the body, the entire stem, disc, and packing assembly can be jacked out of the body by simply turning the handwheel counterclockwise after releasing the gland. No special tools or picks are required to extract the packing. In operation, full opening of the valve exerts an upward force on the stuffing box bushing, thus compressing the stem packing from below - a maintenance feature frequently used to prevent stem leakage until shutdown can be scheduled.

• 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
• 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
