Literally reading this in HVAC2 course, completely confused until I saw your video ( front sealed / back sealed/ mid positioned/ crack open ) the terms in the book make it harder than what it really should be! Thanks brotha !

Thanks Ty! I’m not in the industry but I love to watch these bite sized videos to add to my general knowledge.

Thank you for a great video. Really appreciate it.

Note to self: a KING VALVE is located on the exit of a receiver.
(Thank you for clarifying that one, too.)

Thanks….nice to have clarification on the terminology.

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.

Repairing this value in place is key for R22 systems. Any repair ideas would be good to hear.

I had a tuneup done on our HVAC systems this spring and everything was said to be ok Eight weeks later, one of the units stopped cooling. The same company/technician came out and added 5 pounds of refrigerant and replaced a leaking valve cap which I was told had an o-ring that had basically disintegrated in his hand when removing the cap. I found out on the repair call that gauges were not used to measure the system on the first call but just temperature measurement and a P/T chart. The only repair that was done was to replace the service port cap with a new one. If the Schrader valve was the source of the leak into the failing cap, shouldn't the Schrader valve be replaced or at least an effort made to find the source of the leak and fix it? Isn't just a new cap a bandaid fix?

Ty way called (king) it’s true valve will be enough.🌷

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!

On a typical residential liquid line service valve, is it the same as the suction line where there is that little groove in the front seat position to measure the line set only separate from the outdoor unit from the service port? Thanks.

I live in fear of 'screwing up' here, e.g, cracking a front-seated valve when there's no schrader in the service port (did I get that scenario right?)

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.

Is the service value the main source of leaks on the condenser side of the system?

Is there any option to upgrade the Schrader valve to stop any leakage?
Any seals or process to stop a leak without replacement from the top hex value?

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

How can you know whether a port has a shrader or not?
