QuoteI have this custom built by me 2 stage co regulator.
I know it`s a long shot in Ottawa , but thought i would offer it , just in-case.
The 2 stage chrome Air Gas regulator was bought new.
The fittings are all brass by Swagelok and brass CGA 320 nut and nipple
The solenoid is a Clippard 24 VDC 0.6 amps - this means it has a very low current draw = low heat= longer life
In Line glass bubble counter with tubing and check valve
Needle valve has a couple of options and of course different cost.
Option 1 with Fabco NV 55-18( good valve) = 250.00 FIRM
Option 2 is with a Swagelok metering valve ( better valve but cost more) = 275.00 firm Cdn.
These prices are unheard of as far as custom built 2 stage co regulators and you will be hard pressed to put one together yourself with the parts mentioned for anything close to my asking price.

Very similar build with a different solenoid, same metering valve , same regulator
Note this is just a comparison and not for sale post as the regulator is already sold.
