Yarway Welbond® High Pressure Globe Valve
Welbond

The Yarway Welbond® Valve has become an established stop valve for general line service in modern high pressure power plants. The latest design of the valve combines the proven features of its predecessor with advantages made possible by advancements in metallurgy and fluid flow research. No other valve on the market offers this outstanding combination of features.

It offers industry a value-engineered product with minimum maintenance and maximum service life resultingfrom its unique in-line repairability feature. The one-piece body eliminates all pressure welds, threads, and their related problems.

The extra thickness of the Stellite seat ring eliminates seat cracking and provides for repeated renewal of the seating surface with Yarway’s reseating tool.

The disc is a Stellite investment casting. The design provides a secondary orifice during opening and closing so that erosive forces are dissipated through the disc-body orifice rather than the disc-seat orifice, which must be protected for drop-tight sealing. The body design allows the disc-stem assembly to retract completely into the body, thus assuring smooth flow and a high Cv characteristic. The design of the disc reduces sealing torque for easy operation both manually and with a powered actuator.

Loose Backseat

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.

Threaded-In Backseat

This design offers accessibility after removal of the threaded stuffing box bushing by means of a special Backseat Removal Tool. It requires no seal weld removal for maintenance. A special packing removal tool can be used to remove old packing, quickly, from fixed backseat valves.

  • Fastest In-Line Repair – Repairable in-line more easily and at less cost than any other 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 21/2").
  • Convertible Feature – The complete pre-machining of each Valve body means one of the backseat designs can be converted to the other, simply by reassembly with alternate backseat bushing.
