Hi, thank you for taking the time to cut a valve open and show us the internal operation. I have an HVAC question, regarding the forward mid and backseat silver color valve, is it possible to illustrate the valve internally as you did with the original service valve. Trying to learn as much as possible about refrigeration.

Blue Leak lock on the large hex cap stops that one. (Never put leak lock on the service port cap). Good brass calves cap and shrader core replacement solve the other.
@Nightmare5219918 күн бұрын
I had a few hex service valves leak from the hex head position. Do you think that is from a faulty valve or maybe technicians who put a lot of force when they fully open the valve? I've seen a lot of guys do that. Thanks for the awesome video, these are very educational!

1 thing I didn't hear being mentioned. Not sure if it's true with all companies but Goodman at least considers the cap of the service valve as the final seal, as the valve might sometimes leak a bit. In my experience, after fully unscrewing the service valve, give it a little turn back. I have seen when it's all the way open it sometimes leaks a bit.

Very nice video, thanks for posting. I have a question. You mentioned that new condenser has all the ref. and the valve is in Front seat position. Very true. That's what I have. My piping to and from is complete. Did the vacuum with shredder valve out on suction side. As soon as I open the "top cover off " of the suction service valve, Ilost the vacuum. So that means the suction service valve has to be open half way so that the slot in the stem faces the service port, if I understand correctly. If I'm correct, how to achieve that location. Please advice. I need to solve my start up problem. Thanks and regards.

No, It is new modern unit with L-key and cap. Any how someone told me that valve is damaged due to heat from brazing pipe to it. Neoprene ring is burnt. That is the reason. So he suggested that after vacuuming the system, release 410a from liquid line to break the vacuum. Than open the Low side valve with nice gloves on and quickly. Than put the cap with sealant. Never open again. So I did. Lost little refrigerant. But unit is working now. I Thank you and all those on KZread trying to help each other that leads to Harmony and love in community. Thanks GOD.

I recently ran into a valve on a commercial trane condenser unit that had two service ports with the condenser fan pressure switch on a third port off the bottom. The tech I was working with said it had been left back seated which caused the pressure switch to be closed off to the refrigerant. He said it should be left mid seated to allow the pressure switch to cycle on the third condenser fan on each circuit. Have you seen this valve and does that make sense? Just asking because I cannot find any information on this valve

Yes that is common. I don't like to put stitches or controls on those valves only because the next tech might do just that, back seat the valve and make the switch worthless. Great point

Simplest leaks are service valves, simple to fix. Next would be how well they where brazed in. The evaporator coil is the biggest leak place inside and the discharge line and lower portion of the condensors coil biggest leak outside.
