The reversing valve simplified.

- The simplified version of the reversing valve for heat pumps.
the pipe by itself is always high pressure high temperature superheated vapor form the compressor dischargejne aka hot gas line.
The pipe in the middle of the 3 is always suction, low temperature, low pressure superheated vapor to the compressor.
the reversing valve directs hot gas outside in the summer, and hot gas inside in the winter.

this was the clearest explanation on RUclips for how the flows work, thank you.
Thank you sir. Couldn’t have made this any more simple
Love the little hand 🤣🤣🤣
SAY Hello toy little ... Hand 😂
@@love2hvac hope you bring it along on March 20th 🤣
Thank you for taking time from your day to teach us HVAC. I'm am just starting at 19 yrs and I see how much depth and simplicity you put into teaching. I have just started on watching your Playlist for getting into hvac and watching the fundamentals.
Awesome!!! I love it when people want to learn. I will answer as many questions as I can!
Great teacher thank you for all you do
Thank you! I appreciate that!
Love this
Thanks a million!!
You are very welcome!
It is litely like the steam valve of a steam engine
The sliding cup style
👍
Hey Ty, when are you going to put up the John Gorrie Museum video?
I plan on having it up this month!
@@love2hvac Awesome! I'm looking forward to it. I want to get there myself someday.
Quick question for all the techs out there.... if a unit is low on charge could it cause the reversing valve to become stuck?
Low on charge will not have enough pressure difference to make the valve shift. It needs approximately 100 psi pressure difference.
The Little pilot valve on the back side diverts HP discharge gas to one side of the slide valve and connects the opposite side to suction. The pressure difference makes the main valve move.
So low on charge won't make it stuck but it won't have the pressure it needs to move it.
I have been to nearly 30 reversing valves that were miss diagnosed as bad. They rarely go bad, it's usually something else.
What do you think the lifespan of that valve is? What's the labor effort needed to repair it?
They should out last the system.
In my career I have replaced less than 6 3 from someone overheating and 1 from someone striking it with a hammer. The 2 remaining was from system contamination blocking the pilot tubes.
I have been to nearly 30 that were misdiagnosed. The actual problems being wiring, bad solinoid, low on charge, clogged filter drier, bad compressor valves, stuck check valves internal and external.
@@love2hvac thanks this helps in my understanding of the technology.
What is the process for getting a couple of stickers ???
Well, that's a great question! This is the first time anyone has asked, so I will look into making some!
@@love2hvac you are a very good teacher, I have my 608 universal and look forward to learning more from you. TY Branaman HVACR Classes
@@love2hvac Maybe one with your red/blue compressor/reversing valve as your logo?
