I need to replace the gas valve for my Bryant 234 4PW Series E gas boiler for my home hot water baseboard heating. Where can I buy one and how do I install it?

I am looking for a specific answer to the question of what Gas Valve should I buy to replace my Bryant 1/2 A643 Gas Valve on my 234 4PW Series E boiler. I appreciate the generic response on finding the info and installation (both of which I already know how to do generically) but am look for more specific help since the A643 is obselete.

Thanks - here's a quick update - my HVAC pro finally obtained this replacement Carrier part number EF53CK198 from the Bryant dealer at close to $400! We looked online and found/bought an exact EF53CK198 replacement RobertShaw unit (Robertshaw 700-416 Model 7000BGVER-S36) at around the same price as the unit you found at Grainger. Will let you know when how it fits when I get it installed.

Thanks for your help. I accepted the solution and will be glad to give you a positive rating (except I am not sure how to do that!)

Yup got it! By the way, I bought all the appropriate length pipes and have a question. Here is the sequence of pipes/valve that I have connecting the FIXED supply side T junction on the left (with a Female 3/4") and the FIXED furnace side pipe on the right (with a Female 1/2"):

3/4" x 3" nipple dual Male - TO -
3/4" to 1/2" Reducer dual Female -TO-
1/2" x 2" nipple dual Male -TO-
1/2" to 1/2" valve dual Female -TO-
1/2" x 4" nipple dual Male

Try as I may, I cannot visualize how to connect the last component since it will thread in on one side and thread out on the other!!! Am I going nuts? Yup got it!
