It ought not be a ratio between the surface area of the input valve and diaphragm that regulates the pressure. Were that the case then the output would be a fixed ratio of the pressure in the tank, but a regulator's job is to produce a (nearly) constant output pressure weather the input tank has 200psi in it or 5. I'd suspect that the spring provides the vast majority of the force that the output side works against, with the difference in surface area (And probably leverage from the little lever) ensuring that the ratio of force from the input is "very large". Sufficiently so that the variation of output pressure becomes negligible with expected variations on the input line.

I've never actually taken such a thing apart or done thorough research on these, but that's just a thought that popped out at me while watching this.

Videos like this teach me things I would have never learned in my regular life. Thank you for taking the time to show this.

Just love people who take things apart....this means that they haven't strayed too far away from childhood...great video.

Get a Fisher 912 regulator. It’s what was copied to make this piece of non serviceable junk. You can totally take apart a 912 to clean it, repair it, rebuild it, unplug the orifice, and adjust it to supply more or less output pressure.

Very interesting, I am a Mech Engineer and I always wondered! I showed the video to my 3 engineer kids and one nurse and they all appreciated it!

I was nervously watching you cut the regulator on the band saw and the explosion scared the crap out of me 😂

[timstiles]

Real funny guy, I spilled my coffee on my leg 🤣...
Totally wasn't expecting that from this video... well done Sir...

Quality content. Even though it's a teardown, I'm tempted to point out that this too is what can be considered Right To Repair. It's knowing mechanisms and where to look for problems.

I have wondered what what in there for years. Just finished watching you rebuild seals and piston shafts for your bulldozer. Thanks for the know and fun.

GREAT VIDEO TAKING SOMETHING APART TO SEE HOW IT WORKS. YEARS AGO I TOOK AN ELECTRIC WATER HEATER THERMOSTAT APART AND IT SHOWED A SET OF CONTACTS CONTROLLED BY A BIMETALLIC DISC THAT WOULD OPEN AND CLOSE TO CONTROL THE HEAT. ONLY ONE WITH A TWO THERMOSTAT TANK CAN OPEN AT ONE TIME

On Weber grills if you turn on the burner before turning on the tank it engages a safety device and you get low flame. You can reset it by shutting everything off and starting again. You might try this before changing regulator.

Awesome. I love learning how things we take for granted work.

Thank you: Always like seeing stuff taken apart!!! Your crossectioning made it even better.

The ball bearing also stops the flow in a high flow situation like if the low pressure hose is cut.

The ball bearing can also prevent too high of a flow into the regulator and can sometimes become stuck partially restricting flow. You can reset this by removing the regulator from the tank and letting any gas in the regulator reset the ball valve. You might not have needed a new regulator in the first place.

Subscribed!!!! I have always wanted to open one of these up but didnt want to lose my fingers. Thank u for risking your fingers. My only question is what happens if the little breather hole to the outside air gets clogged? Should we stick a pin in this breather hole to see if it will solve a low flow situation?

I'm New here but I enjoyed the video greatly. Say hi to Kevin

[rickcgag]

wow you almost knocked out of my seat (didn't expect that). :p

[galaxianentity]

Years ago my regulator crapped out on me so I bought a new one and tore apart the old one much like you did - but was able to put it back together -and it worked !!! I used the new one just to be safe. The problem seemed to be the ballbearing crapped up with carbons in the propane - but yeah - it worked fine !!!
