Yarway 5617B 3/4 1124935

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 resulting from its 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.

Yarway Welbond® High-Pressure Globe Valve, Model: 5600, 3/4 in Nominal, NPS Connection, Socket Weld End, 1700 psi, 1700 lb Pressure Class, Water Media, Carbon Steel Body, Stellate Seat, Stainless Steel Stem, Stellate Disc, Graphite Packing, Iron Handle, T-Handle Operator, 6 Cv Flow Coefficient (Cv), ASME A105, ASTM A582 Type 416, AMS 5385 Material Standard

• 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
• One-piece forged body without pressure welds, seal welds, pressure containing threads or gaskets, body/bonnet joints or any of their related problems
• 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
• 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 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
