FEATURES• Fastest in-line repair – Repairable in linemore easily and at less cost than othersimilar valve. Stem, disc, and packing canbe quickly removed through the yoke, andthe seat fully exposed for "like new"restoration.

• High dependability – One-piece forgedbody without pressure welds, seal welds,pressure-containing threads or gaskets,body/bonnet joints, or any of their relatedproblems.

• Greater durability – Solid Stellite® discand seat ring all but eliminates cracking.Extra thickness of the seat ring alsoprovides enough material to renew theseating surface over and over again.

• High flow capacity – Generous port sizesand disc retraction well beyond thatrequired for optimum flow. Thesefeatures help to minimize flow velocities,and therefore, decrease the erosiveforces, which shorten the life of the seatand disc.

• Available off-the-shelf – An in-depthstocking program makes Welbond®valves available to you directly off-the-shelf (socketweld ends standard to 21/2").

• Convertible feature – The complete pre-machining of each valve body means oneof the backseat designs can be convertedto the other, simply by reassembly withalternate backseat bushing.

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 withadvantages made possible by advancementsin metallurgy and fluid flow research. Noother valve on the market offers thisoutstanding combination of features.

It offers industry a value-engineered productwith minimum maintenance and maximumservice life resulting from its in-linerepairability feature. The one-piece bodyeliminates all pressure welds, threads, andtheir related problems.

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

The disc is a Stellite investment casting. The design provides a secondary orificeduring opening and closing so that erosiveforces are dissipated through the disc-bodyorifice rather than the disc-seat orifice,which must be protected for drop-tightsealing. The body design allows the disc-stem assembly to retract completelyinto 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 BACKSEATThis design offers the greatest accessibility,thus is the easiest to maintain, especiallywhen complete removal of the stem packingis desired.

Because the stuffing box bushing is notfastened to the body, the entire stem, disc,and packing assembly can be jacked out ofthe body by simply turning the handwheelcounterclockwise after releasing the gland.No special tools or picks are required toextract the packing.

In operation, full opening of the valve exertsan upward force on the stuffing box bushing,thus compressing the stem packing frombelow – a maintenance feature frequentlyused to prevent stem leakage until shutdowncan be scheduled.

Loose backseat models are available in sizesshown on page 8 for Classes 1700, 2700 and4500. Corresponding figure numbers areindicated. The appropriate figures should bespecified when ordering.

THREADED-IN BACKSEATThis design offers accessibility after removalof the threaded stuffing box bushing bymeans of a special Backseat Removal Tool. It requires no seal weld removal formaintenance.

A special packing removal tool, availablefrom Pentair, can be used to remove oldpacking quickly, from fixed backseat valves.

Threaded-in backseat models are availablein all sizes shown on page 8 for Classes1700, 2700 and 4500. Corresponding figurenumbers are indicated. When ordering thethreaded-in backseat design, use suffix “B.”

PRESSURE AND TEMPERATURE RATINGS



Without cutting the valve body out of theline, the stem/disc/packing assembly canbe jacked out in minutes for inspection orreplacement of the packing rings. Withbody still in place, the Welbond reseatingtool can be mounted through the yoke, forthe establishment of wholly new seatingsurfaces. Normally, the reconditioned andreassembled valve can be back in service inless than an hour without cleaning,welding, radiography, and other operationsassociated with the maintenance ofconventional valves.

The reseating tool comprises a shaft with aremovable tungsten carbide cutting headon one end and a handwheel on the otherend. These components plus a key forremoving the head are supplied as a kit.Complete lists of tools for all valves can befound on these pages.

After removing the weld that secures theyoke bushing, the bushing is unscrewed andthe stem is backed out. Then the tool isinserted into the valve body and slowly fedinto contact with the seat by means of athreaded-feed screw that engages the yokethreads.

With the cutting head against the valveseat, a locknut is tightened to prevent toodeep a bite into the Stellite seat material.When the wheel turns freely, the locknut isreadjusted to permit a new cut. After five orsix turns, an entirely new seat has beenmachined. The tool cuts both inclinedportion and throat of seat to give acompletely new line-contact seal.

WELDING OF WELBOND VALVESSince the welding procedure is dependentupon various codes established by users,contractors and government rules,qualification to the specific code involvedshould be followed during valveinstallation.

The valve should be full closed duringwelding.

Installation welds made in accordance withASME Section I and ANSI B31.1 are exemptfrom post-weld heat treatment as long asthe preheat and exemptions of these codesare followed.

Reseating tool is lowered into valve body afterremoval of yoke bushing and valve stem.

After tool locknut has been tightened againstyoke face, to prevent too deep a bite into seatmaterial, seat can be reconditioned by meansof a series of five or six slow cuts.

New stem/disc assembly is lowered into valvebody after completion of reseating cuts.

POWER ACTUATIONWelbond valves can be fitted with electricmotor actuators for remote or localautomatic push button control. With thisaddition, valves installed in elevated pipingruns, or where an emergency will requirerapid, positive, and remote operation, canbe quickly controlled.

Motor actuated valves are available in thesame sizes, materials and pressure classesas manually operated valves. They usestandard repair parts, which areinterchangeable with manually operatedvalves of the same size and pressure class.

Motor actuators include position switches,torque switches, and auxiliary switches for

audible or visual signals at the panel board.Dial indication of stem travel is alsoavailable.

Valve actuators are designed to provideconstant seating thrust. This helps ensure drop-tight closure and automaticcompensation for valve wear. A handwheelis provided for emergency operation in theevent of power failure.

Pneumatic actuators, in both fail-open and fail-closed models, are also availablefor remote operation of Welbond valves.Manual handwheels, limit switches,solenoid valves and air filter regulators can be provided.



HOW TO CHANGE FROM MANUAL TOMOTOR OPERATED VALVEA Welbond valve already installed on field can be quickly changed from manual to motor operated by means of an auto-alignment adaptor plate. Adaptor plates are available for all Welbond sizes from ½" to 3". Please refer to your salesrepresentative for further details.

When ordering an auto alignment mountingplate please specify valve size, class valueand actuator type and brand.

1. Loosen the gland nuts.

2. Remove the tack weld from the bushing yoke.

3. Unscrew the yoke bushing.

4. Screw the mounting plate kit.
