How a gas regulator works

In this video we will look at the mechanism inside a gas pressure regulator.

Pressure regulators are critical components used with gas appliances. They reduce the inlet pressure from high-pressure sources like tanks or pipelines to the desired lower outlet pressure suitable for applications such as heating and cooking.

They serve as essential safety devices by maintaining a steady outlet pressure to the appliance, regardless of fluctuations in the inlet pressure, and automatically cut off the gas flow when it reaches a certain pressure, preventing pressure spikes.

Holy crap. 5 minutes, no stupid sponsors, no bs. And I learned something. This is what YouTube should be. Thank you.

Pretty Good Video
Here are some corrections/additions:
1. Natural gas is methane and not considered a Liquified Petroleum gas.
2. Liquified Petroleum gases are: Propane, Butane, Iso Butane, etc.
3. The access cap for the regulator adjustment is righthand threaded - not left hand as was shown.
4. The gas regulator shown in the video is very basic - like the one on your gas grill. Almost all gas regulators provided by gas utility companies have a threaded vent port, so that the screen can be removed and small diameter pipe and fittings can be used to direct the vented gases outdoors (if the regulator is installed indoors) or if installed outdoors, to direct the opening down so rain does not enter the vent port. That way the regulator can be installed horizontally as well as vertically.
5. Larger gas regulators (like the one's on most homes and businesses installed by the gas utility) have interchangeable gas metering orifices and adjustment springs. Changing the gas orifice size, changes the volume of gas that can flow through the regulator, while changing the spring stiffness, changes the range of outlet pressure adjustment capability.

The arrows exist in the same 3d space and cast shadows and reflections! You madman! That's a very little detail many won't actively notice but it adds so much! These videos are great in their explaining and visuals

Excellent video. As long as it needs to be and no longer. No useless intro about what the video is going to contain, no history of regulators, no intrusive music and no ai Voice over. Well done mate

[J_CtheEngineer]

Having installed and replaced *hundreds* of these, this kind of detail really helps me understand the exact operation and potential failure modes. Thanks!

Such a beautiful simple design. I love these self regulating mechanical concoctions

[BeeHiverson]

The golden age of YouTube! Interesting informative and not jammed up with garbage adds and product pusher!

[TheNerogarden]

I love this channel. I probably will never user this information but I can't help but to find it fascinating. Makes you appreciate the human ingenuity

[EATSLEEPDRIVE]

A short, informative, no BS video. You've earned my subscription.

Brilliant summary. I didn't realize it uses atmospheric pressure as the baseline, which will shift up and down depending on atmospheric pressure. That makes sense because at the outlet burners, flow of gas out will also depend on the relative difference between line pressure and atmospheric pressure.

This is one of the most ingenious inventions *ever*. Goes hand to hand with the differential.

[brianbender]

Wow, was that perfect! Good explanation and incredible graphics. No obnoxious music or stupid jump cuts. This is a textbook example of how it should be done. Thanks.

Your videos are TOP NOTCH. 10/10 every time. Keep it up!

Couple points. The relief valve is a safety device in case the seat disk does not close off 100%. If it is venting at all, then a repair is in order.

How did I not come across this channel before? The answer to the question that has long tormented me is short, clear, understandable, and much more detailed than I expected. Thank you!

[daniellimamota]

One of the best channels I've found recently

4:39 dual stage regulators is for safety and control. Typically when there's a very large pressure difference and /or a very wide variability of the inlet pressure. It's one valve body, so it does not help to compensate for distance.
Multistage systems are used used when you do need to deal with distance. You have 2 or more physically separated regulators. Propane is typically 2. (no less no more, not including the appliance regulators) NG will be dozens in series at the very least, most controlled by the utility.

what a relief among all the hate video recomendations.. subscribed

[deadblazer]

That's so clever! I've learn something tonight.

[charlesbartlow]

I subscribed at 1:31 when i realized...dis guy is all facts no craps lol thank you for making this video. Now i can fix my forge and foundry regulators ❤
Many thanks good sir!
