It's a red handle gate valve with harvard wrote on the side need to find replacmet parts

What part do you need?

Answer Ballenger's question, but any Harvard gate valves I ever purchased were back in the 70s/80s and were only available at a PLUMBING SUPPLY STORE, so I would recommend that you check in at your local supplier and see what they can find for you.

Otherwise, as I am sure you are aware of, you may do well to simply replace the entire valve... not so hard in most cases if you use a UNION fitting to make the swap out... ;)

The gate and the stem for two inch

Can anyone suggest where to get new stem and gate?

That's very hard to match... You will be better off replacing entire valve... Milo
