WELCOME TO
THE STANDARD OF SAFETY.
A.Y. McDonald designs and manufactures our natural gas products to comply with several industry standards – ASME, ANSI, and ASTM. But as of May 1, 2015, we took this a step further by starting to mark A.Y. McDonald natural gas products with a new barcode that was developed in the new ASTM F-2897-14 standard. As a real game changer, A.Y. McDonald is one step ahead when it comes to our commitment to gas safety and accountability through the use of traceability tags!
New times, new technology Making accountability easy
General Information
Thanks to traceability, city streets and backyards can be a whole lot safer. With innovation and organization at its core, the ASTM F-2897­14 standard determines the information gas distribution products are marked with. In the event of an accident caused by a gas leak, gas utilities can access this information to locate other potentially faulty products. Through inspections and necessary replacements, we can prevent future accidents.
To make this standard of traceability convenient for you, A.Y. McDonald has made TRACE TAGS standard on each and every gas valve and meter bar we manufacture. These products come complete with a barcode detailing the type of material the product is made from; component details; and the date an A.Y. McDonald employee in Elizabethton, Tennessee, Albia or Dubuque, Iowa, machined, assembled and tested the product.
EVERY PART. COMPLETELY ACCOUNTED FOR.

Natural Gas Ball Valves
Natural Gas Meter Ball Valves
175 PSIG BALL STYLE METER VALVES
Precision machined and offers bubble tight leak protection both open and closed. Ball Valves offer the added feature of lower and more closely controlled operating torques for the life of the valve. The brass ball rides between two PTFE port seals that require no lubrication. The stem has a double o-ring seal and cannot be removed from the valve. The body and endpiece threads are pinned to prevent disassembly
without damaging the valve. No eld adjustment or maintenance of this valve is needed.
All connections with pipe threads require use of thread sealant at installation. (PTFE tape is not recommended, see instruction sheet.)
Additional Features:
- A.Y. McDonald’s Iron Body, Brass Ball Valve is designed and tested to comply with ANSI/ASME B16.33 American National
Standard for “Manually Operated Metallic Gas Valves for use in Gas Piping Systems up to 175 PSIG.”
- Soft seat design does not rely on grease to prevent leakage to the atmosphere or through the valve seats. Sealing capability is maintained even after many cycles.
- Tamper-resistant (Tamperproof) design makes the A.Y. McDonald Ball Valve virtually impossible to disassemble without
making the valve unusable, i.e. pinned end piece requires excessive force to remove and valve cannot be reassembled if forcefully disassembled. The valve utilizes an internally loaded operating stem. The external cap is secured with a tamper- resistant stainless steel screw.
Ball Style
- Breaking torques are closely controlled in excess of what can be turned “by hand” and yet low enough to ensure easy turning
with a small wrench. Easy turning remains for normal life of valve.
o
rotation provides complete shut-off from the open position. Valve can be rotated full 360o.
- A 90
- Pressure may be applied in either direction as A.Y. McDonald's Ball Valve is a non-directional valve.
- Traditional lockwing design easily accommodates standard Barrel-Locks or padlocks.
- Full Port openings accommodate the best known stop changers and yet provide less ow restriction than non-circular
openings or valves with reduced ports.
- Ball valve design isolates operating cap/stem seals and main shell from internal line pressure when the valve is in the normal used, full open position. Sealing against external leakage during this normal service is thereby doubly-provided and the stem seals do provide the necessary external leak protection during cycling.
- In the normal open position, the sealing surface of A.Y. McDonald’s Brass Ball is isolated from the probable contaminants by the port seals. This results in a more reliable shut off over the life of the valve.
- In addition to an o-ring, metal-to-metal positive seating of the end piece limits the squeeze on port seals, and serves as back-up seal if necessary.
- No eld adjustment or maintenance required.
- Each valve is pressure tested in both directions electronically.

- Temperature Range: –20
- Available in FNPT x FNPT (860) or FNPT x Insulated union (8276).

Re-Lubrication Tool
FOR USE ON 175 PSIG RE-LUBE VALVES & WITH A.Y. MCDONALD GREASE ONLY
A.Y. McDonald Mfg. Co. model number 558 Re-Lubrication Tool is an easy and economical way to lubricate 175 PSIG gas meter valves. The tool is machined from steel alloy for durability and has an Allen wrench mounted to the body for convenience. It can be used to re-lubricate
A.Y. McDonald valves in the full open or the full closed position when the valve is pressurized or unpressurized. It will also lubricate valves of other manufacturers. Check with them for their recommended procedures.

tool, stick a piece of wire (smaller than opening
on end of tube) through the bottom section of the re-lube tool until the wire comes out the opposite end) reassemble the top section to
plug re-lube port, and continue to turn the "T" Handle clockwise to force the A.Y.
McDonald Lubricant into the valve. Caution: Re-lube valve carefully to insure the valve is not over lubricated.
Unscrew "558" Re-Lubrication Tool by turning counter-clockwise until there is

only a couple threads left engaged. Turn "T" Handle clockwise to add a little more grease to ll void left in head of plug from backing off the tool, then remove tool completely from valve (put tool back into container to avoid dirt or foreign material
from contaminating grease on tool).

After re-lubrication of the valve is

Remove the 1/8" NPT Allen Head Pipe Plug from the re-lubrication port
4
in the head of the plug.
NOTE:
- A small amount of gas leakage may be observed from the re-lube port while performing this procedure, based on the amount of grease left in the valve prior to the valve being re-lubed.
- Other commercially available re-lube tools may be used, but you must check with the factory before using.
- The eld Service Personnel, after a few trials, should be able to tell by the feel (resistance) of the handle, when the stop is lled has a
adequate amount of grease in it.

Angle Ball Valves
5 PSIG 3/4” & 1”, 25 PSIG 1 1/4” ANGLE BALL STYLE METER VALVES
Precision machined and offer bubble tight leak protection both open and closed. Ball Valves offer the added feature of lower and more closely controlled operating torques for the life of the valve. The brass ball rides between two PTFE port seals that require no lubrication. The stem has a double o-ring seal and cannot be removed from the valve. The body and endpiece threads are pinned to prevent disassembly
without damaging the valve. No eld adjustment or maintenance of this valve is needed.
All connections with pipe threads require use of thread sealant at installation. (PTFE tape is not recommended, see instruction sheet.)

Positions B & C are possible pressure tap locations. Please refer to Block 5 for pressure tap options.

Inlet
INLET AND OUTLET CONNECTIONS
NPT inlet tapping provides a solid connection directly into the valve. Outlets are available with NPT integral or union type connections.
Union connections have a at rubber gasket or an o-ring seal.
- Soft seat design does not rely on grease to prevent leakage to the atmosphere or through the valve seats. Sealing capability is maintained even after many cycles.
- Tamper-resistant (Tamperproof) design makes the A.Y. McDonald Ball Valve virtually impossible to disassemble without making the
valve unusable, i.e. pinned end piece requires excessive force to remove and valve cannot be reassembled if forcefully disassembled. The valve utilitizes an internally loaded operating stem. The external cap is secured with a tamper-resistant stainless steel screw.
- Breaking torques are closely controlled in excess of what can be turned “by hand” and yet low enough to ensure easy turning with a
small wrench. Easy turning remains for normal life of valve.
o
rotation from the open position places valve into bypass position.
- A 90
- In addition to an o-ring, metal-to-metal positive seating of the end piece limits the squeeze on port seals, and serves as back-up seal if necessary.
Bypass Ball Valves
- Traditional lockwing design easily accommodates standard Barrel-Locks or padlocks.
- 1” is reducing port.
- No eld adjustment or maintenance required.
- Each valve is pressure tested in both directions electronically or with air under water.

- Temperature Range: –20 Note: These valves are intended for use with natural, manufactured and L.P. gas only.
