Verifying TXV capacity
I ordered a 1/4 ton R22 TXV (actually two) and it had a sensing bulb just a little smaller than a C battery. Thinking I might have got the wrong item or it was mislabeled, I decided to open it up to take a look at the actual valve assembly. To my surprise, the orifice was just big enough to stick a piece of AWG22 wire in it. Is that about right for a 1/4 ton R22 TXV? (There is an inscription on the valve that says 1/4, but I wonder if it was mislabeled. I would hate to carefully put together the system only to find out that the valve is completely wrong!)

Re: Verifying TXV capacity
What number is stamped on the orifice? 00 or 01?
To the optimist, the glass is half full. To the pessimist, the glass is half empty.

Re: Verifying TXV capacity
As an update, I installed the valve and it worked great.
