Series 45: Ductile iron gate valves

The Series 45 valve is our all ductile-iron valve that meets or exceeds the requirements of AWWA C509. Since they are all ductile iron, they also meet or exceed the requirements of AWWA C515. Valves are available in all end configurations including grooved ends, tapping valves, and OS&Y. Every valve is 100% tested beyond AWWA C509, including low pressure testing. All valves are certified to NSF 61 and NSF 372, meeting all requirements of the Safe Drinking Water Act.

Features

AVK bolting and gasket system

• 316 stainless steel bonnet bolts will never come in contact with water or soil and are 100% protected against corrosion
• Unique gasket has round inserts for bolts, which are countersunk into the tapped valve body and capped with hot-melt
• Easily disassembled after years of service - but, you’ll never need to...

Stainless steel stem

• 400 series Stainless Steel is AVK’s  standard stem material, providing twice the yield strength required by AWWA; Potential for bent and broken stem is eliminated
• Threads are cold-rolled, work-hardening the steel, and ensuring smooth thread edges for low operating torque
• Unique wiper-ring protects stem from contact with soil and water

EPDM wedge w/ captive wedge nut

• Standard EPDM wedge is taste and odor free, stands up to chlorine and other disinfectants
• Wedge nut is fully encapsulated in the wedge, resulting in efficient mechanical motion and 10X the open/close operations vs. competitors; Provides higher torque resistance and prevents rubber wear and leakage

Serial number

• Every AVK valve has a unique serial number engraved on the stem – also shown on the valve label; Serial number provides complete traceability to the date the valve was built, and every operation performed throughout the manufacturing process
• AVK is the only gate valve and fire hydrant manufacturer in the USA with a Quality Assurance program that requires serializing every product for traceability

Anode lug

• Unique tapped lug and set screw provide a metal-to-metal termination point for cathodic corrosion protection
• Can accommodate up to 2 - #10 AWG and may also be used as connection for tracer wire

Anti-rotation T-bolt lugs

• T-bolt lugs keep T-bolt heads in position for secure installation of all bolted MJ connections

Both could be used. Under equal circumstances the best (material-wise) should be used, which is the nodular cast iron.

The question is actually if you have any other parameters present in this case to be considered, creating 'un-equal' circumstances, giving preference to one or the other, or perhaps even better materials or products.

Other parameters on the most obvious side could be price, demand (short time, one off replacement up to fabrication and use of larger numbers over a longer time periode), general fabrication quality of the two valves compared, inner surface and surface quality, possible discounts and dependability and quality of supplier etc. etc.

.... Oops! Sorry about that, misread carbon steel as cast iron! My answer is generally still valid, but of course the carbon steel body is better (and cost a lot more) than nodular cast iron.

Ductile iron should be sufficient for a glycol-based water process, and far cheaper. If there's nothing exceptional about pressure / temperature, then ductile iron will do job fine.
