Welbond® High Pressure Globe Valve

The Yarway Welbond® Valve has become an established stop valve for general line service in modern high pressure power plants. The latest design combines the proven features of its predecessor with advantages made possible by advancements in metallurgy and fluid flow research.

• 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-the-shelf (socketweld ends standard to 2 1/2").
• 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.

ARC® Valve For Centrifugal Pump Protection

7100

Yarway ARC valves are the industry standard for centrifugal pump protection.  These sophisticated valves are designed to provide four critical functions in a single valve: 1. check valve, 2. flow sensing element, 3. bypass flow control, 4. multi-stage pressure letdown device.  This "4 functions in 1 valve" design eliminates the need for multiple components, multiple vendors, uncertain responsibility.  There is also no requirement for instrumentation signal or power source.  One valve does the complete job.   Flotech represents Yarway ARC (Automatic Recirculation Control) Valves in Florida, Georgia, South Carolina, North Carolina and Virgin

Hy-Drop Throttling Valves

Yarway Hy-Drop valves are designed for throttling service and controlling high pressure drop service without adverse corrosion or erosion of the valve integrity and function.

The Hy-Drop® Throttling Valve embodies a unique concept, which so controls the destructive forces inherent in high-pressure-drop service that deterioration of parts is virtually eliminated. Rapid energy dissipation is essential to the throttling process, and the Hy-Drop® valve actually encourages this at the same time containing its destructive capability.

The Hy-Drop® Throttling Valve is designed for continuous blowdown, but also works well for sampling, high pressure vents, boiler feed pump bypass relief, high pressure drop services associated with erosive and wiredrawing characteristics—or where velocity is sufficient to destroy valves of conventional globe or even venturi designs

Sizes: 1" and 1-1/2"
Class 1700 and 2700
Forged Steel (A105) or Alloy (F22) construction
