I never grew older than five. At that time I asked my father many many question, curious how things worked. Your "WHAT MAKES IT WORK" video's are perfect clear answers. Really marvelous!. Thanks from the Netherlands.
I always like your cutaways they are extremely useful in gaining a better understanding of how things work. You are an excellent teacher, thank you for all your videos.
There was a time, about 10+ years ago that I feared so much engineering and practical skills would be lost, as the following generations seemed so fixated on computers etc. How lovely to see so much knowledge preserved via You Tube. I have progressed personally so much as an Artisan due to You Tube. Thank you for sharing your knowledge
Great job with the explanation and the cut aways. I spent my whole life in refineries and chemical plants with thousands of valves and I know what is inside but I still found this video interesting. I wish you had also had a butterfly valve. Thanks for the video.
Domestic gas supply is actually regulated to only around 4oz or .25 psi on the house side of the meter. I've always been fascinated thinking of how they cast these valves. Great video, keep up the great work!
As a very experienced Senior Marine Pipe Designer I can vouch for pretty much everything you said. Only thing additional worth mentioning is globe valves are meant for applications where throttling is desired. For standard potable water use very few modern homes make use of Gate valves in lieu of Ball valves however rarely do they spend the extra $$$ for a full flow Ball valve. In general the cheaper ball valve is acceptable, just not optimal. As for Gate valves, they should be treated like a light switch; it's either off or on and NEVER used for throttling as the seat will erode over time. Gate valves are preferred over Ball valves for there ability to provide a true positive stop in the closed position.
I noticed your propensity to create cutaways of interesting mechanical devices! That is something I like to see. Those ball valves seem to be a very good option in modern times. They seem to be less likely to leak through (not close all the way) and also they don't seem to get stuck and frozen up over time when not used much. When the valve is open, the water passes through the ball port and none of it circulates around the stem to leak there or build up sediment there.
Mr. Pete thank you for the valve video. I've always understood regarding the function of the various types of valves, but never took the time to think about the details. Your a good teacher, you make think.
There is something very fascinating about cutaways, thanks for taking the time mrpete. These "how it works" vids are teaching me a lot about things I thought I understood!
Mr Pete! Great episode sir! You definitely didn't talk too much. I wish I had a shop teacher like you back in high school, definitely keep at it, these are the best
+mrpete222 Just came back to this 2 months later because it was relevant to some stuff I was doing around the home. Thanks again! I love your other videos, they're gold, but these are platinum!!! Do more.! Thanks for the millionth time.
Again another well worth doing video. we all seen valves before yet wondered why the difference & advantages of each type & for what application. Another good one Mr.Peterson, Thank you again.
Great video. One can tell you were a teacher - your lesson plan is always in place and flows smoothly. The gas valve you show is a "plug valve." These were used for low pressure applications such as natural gas where leakage could not be tolerated. The nuts on the bottom allow the tapered plug to be pulled into a tight seal. Plug valves always require a grease style lubricant to operate. Today, plug valves have pretty much been superseded by ball valves. Ball valves can be designed to be gas-tight and still operate at high pressures.
Have you ever thought about doing a video on the water valves of a clothes washer? It's pretty neat how they stop the full pressure of the house's water lines with only the plunger of a solenoid and a weak tiny spring. (at least that's how my Whirlpool did it). I love how you will sometimes say "I won't cut this away.. it's too much work" or "I won't take this apart" and you end up doing it anyways. I'm glad you change your mind. Great series, keep em comin' !!!
Excellent as always Mr. Pete! Your teaching aids are always helpful in showing along with explaining how things work. I don't like plastic valves either, nor plastic piping for that matter. My house was built in the '40s so it's all iron pipes except what's been added in the past 20 years, (PVC). When it gets below freezing just guess which pipes give me troubles...
+ShysterLawyer I can guess. It's the ones that were not insulated or routed properly. I have almost all plastic pipes and have never had a freeze up because I know that dollar store pool noodles make better pipe insulation than that hygroscopic, expensive sponge rubber they sell in the hardware stores. Unfortunately it is usually too small a hole to fit most iron pipe without splitting and doubling up. Mike (o\!/o)
I really like cutaways. My shop teacher in high school made a cutaway of an old Briggs & Stratton engine. It was fascinating. I didn't know the parts in an engine moved so fast.
i worked for an elevator company that primarily did "ram and jack" type installations (the car is lifted by hydraulic pressure. generally, 4 stories and less). the cutoff valve between the compressor and the jack was a single large brass ball valve. worked pretty well.
Hi Lyle, we are gradually changing over to "single action lever valves" these are self cleaning ball valves with a 90 degree on/off action and the flow can be restricted accordingly, every time the valve is operated the face of the ball and the seats automatically clean themselves and are so much more efficient in times of emergency shut offs, ie, it only takes a second to stop the flow, I have them installed all over my house.
Thanks for the dissertation on valves. If you look at the top of the gate for the gate valve and the bottom of the bonnet of the gate valve you'll notice that it is machined so the valve can be "back seated" when it is opened to prevent leakage through the bonnet and the packing
Another great video Mr. Pete! I love'm all. However, the little cap with a hole in it on the outlet side of a valve (usually called a "freeze valve" when used in conjunction with a hose bib type valve outside), is as you stated used to drain the water between the two valves to prevent freezing, although not in the way you described. No water should ever actually come out of the hole, nor should the cap ever be completely removed lest it become lost. That's what the little hole in the cap is for, it's an air hole. It should be cracked open after shutting off the valve to break the atmospheric pressure holding any water still in the pipe connected to the hose bib outside. Yes, you're going to have to man-up, brave the elements, go outside, and open the hose bib to let the water drain outside, not inside on the basement floor. Newer homes simply don't have basements or even crawlspaces to allow access to classic freeze valves, so a "frost free" valve with the valve seat on the extended end thru the wall inside on the warm side is used. These valves most often employ a built-in atmospheric breaker that not only facilitates draining the water from the attached hose when the water is turned off, but also from the valve extension inside the wall to keep it "frost free". By the way, I'm a retired applied physics instructor and technical writer, and have used cut-aways extensively in my career to illustrate the inner workings of everything from simple pipes, to complex aircraft engines. So, I love your use of cut-aways to get your point across. Keep those videos a com'n!
+Tom Clark Thanks for watching--thats very good info. I can tell you know what your talking about. I wish I had a better physics back ground (or in fact remembered my physics). I have always loved cutaways & thats why I make my own. And I will make many more
You know when the video first started, I thought "oh... valves.... boring...". Then I realized I didn't know how they worked so I learned something! I would have liked to have to have seen the ball valve cutaway. I can't figure out how they seal. Hey Mr. Pete - ever see the British show "The Secret Life of Machines"? If not, try to find it somewhere. Not a lot of episodes but the quality is there...I think you would enjoy it. Probably a little dated by now as they did one on fax machines...
it's always best to turn your main water valve off and then on once or twice a year to stop it seizing up.. thanks for the video sir great as always...
+mrpete222 its just one off them things that people don't think twice about.. but doing it can save you a lot of money in repair bills when it does seize up...
Globe valves are still made with no rubber seat. They cost more, as the seats are ground in and there is more metal involved. They are used for service where the rubber seat is not suitable, such as oil and steam. My favourite use for the stop-and-waste (valve with the drain hole) is expansion tanks. It is nice to have a way to relieve them to reduce the mess when unscrewing the fitting after they inevitably fail. I have also seen them used back-to-back for isolation in steam and chemical systems. The waste ports are facing each other and are opened to relieve the short section between the valves after the valves are closed, to prove that pressure is relieved and isolation achieved.
Hey good video. As long as you like doing this perhaps you would like to make one about normally open and normally closed gate valves. Most people don't know the difference it would be intereting
That was interesting nomenclature. We always called the multi-turn valves 'Gate' the quarter turn valves 'ball' and the plastic ones 'junk' because they are suppose to hold the water back and after a year they do not.
valves with nipples are also used to relase pressure when solding pipes when water is present and the vapor would pressurize and make the solder wicking difficult
Excellent video .... I actually have used gate valves to control the flow rate ... they do a much better job. Also, I'm gradually replacing the valves in our old house with ball valves. They're much less aggravation. I enjoy your use of cutaways. They remind me of the old days in museums.
Appreciate your videos... FYI, though, natural gas is typically 7 inches water column or about .25 lbs pressure and LP gas is 10-11 inches water column.
+George Hoffman I have 2 valves that disprove that notion and some new valves are only marked by the paper tag. Both being relatively new it may have been a standard that has been abandoned by some. Best practice is if the casting is not marked just look in the ends and feed in on the lower side. Mike (o\!/o)
Hey Mr. Pete -- I'm that 60 yr old guy at the hardware store, BTW -- does anyone know exactly what the synthetic seating/packing material in ball valves is and how well it holds up over time? I've only had experience with ones that have been in service for 15 years or less.
These days, I make all my exterior values using the nylon and stainless steel 1/4 turn ball valves. Shut offs and even hose bibs. They never leak and turn off immediately! :D
Love your videos Mr Pete. Your voice and presentation style remind me of my father. So similar! He taught me so much in our garage workshop growing up. Things I now teach my boys.
You don't have to open it all the way, gate valves are preferred to globe valves for limiting flow. Ball valves are the least preferred for limiting flow as they cause a lot of chatter with butterfly valves being the best for limiting although they don't hold pressure.
Can always learn something new from these videos, good job Mr Pete, A WW2 navy submariner always taught for hand operated globe and gate valves that have non rising stems that are left open, always back seat fully and then front seat 1/4 turn as this allows immediate proof of the open position as valves fully back seated tend to mechanically freeze, when needed to operate - impossible to tell if open or closed. Rising stem valves allow visual proof of valve position, certain applications mandate these. Most old timer boiler men always wanted gate valves installed with the gate in the horizontal position when possible so sediment would not accumulate in the bottom of the gate slot. Also most codes no longer allow plug type gas shutoff valves.
Have learned a lot of knowledge, if the manual production of a miniature, what kind of program should be used, thank you！！！！My English level is not good，lalalala
great tips. there's one valve you need to ck twice a year or so it's your water heater pressure valve ..it's very dangerous if it don't work right. it's like a rocket in your basement
I prefer ball valves and have replaced most of the globe valves in the house. Primary reason is the globe valves (almost 60 years old) leak like crazy once you touch them! My preference is because a ball valve only needs a 90 degree turn to shut the flow and they're sealed and easily replaced if you can sweat pipe. You don't have to turn ad infinitum and wind up with a wet shirt sleeve from overhead. The ball valves are pretty easy to use while the lever is in-line with the pipe, the flow is on and if it's perpendicular to the pipe, all bets are off. My house has full city pressure ~90 psi and I haven't had any problems with drop-off pressure. I would never consider plastic pipe, ever! My mother's house is plumbed with plastic and the pressure has to be cut significantly because everything is glued, except for the sprinklers. Taking a shower in her place is like having someone piddling on your head. Tragic. Outside valves on the hose bibs are another story. I'm a little hesitant about replacing them for two reasons. First, the proximity to concrete walls and second, going through the concrete walls. Sure, I can make extensions but is it worth anything? Probably not so they'll be just fine if they drip when I'm washing the car or watering the grass.
That gas valve is called a spring valve and they are terribly dangerous because they almost always leak, having largely been supplanted by ball valves.
Those globe valves are more the one usage type, after being installed, the day you need to use them like 10 year later they WILL LEAK all over, time for a ball valve.... ;)
Every time I need to service a globe valve on something I have control over, they get replaced with quarter turn ball valves with waste ports. It's just courteous to future repair folk. Also they are much easier on the hands and wrists, and nobody is getting younger.
Don't just throw those away. Give them to someone who can teach others, maybe even give them to kids. As a kid I would've rather played with a 3d object than watch a video.
"throw this away in 15 minutes"????!?!? that's BRASS.....my grandfather kept a bucket of old brass fittings like that, he'd take them apart so it was all brass.....then, it was either melted down as source material for casting, or turned in for recycling, since brass usually carries decent rates: a bucket worth of "sorted" brass, would be worth ~$1.5 a pound, so a bucket is likely worth $20 or more..... (personally, I'd keep it for casting... ;) )
While watching this video, I was saying that this is a good training video for work on gate and globe valves. But that went out the window when you made a general statement about young females not being up to date on valves because they sit around texting. I know these are yours vids, but these statements sucks.
Mr. Pete, you are a true artisan. Thank you for all your videos. You have the heart of a teacher. Thank you!
+Raymond Clark THANK YOU VERY MUCH.

Can always learn something new from these videos, good job Mr Pete, A WW2 navy submariner always taught for hand operated globe and gate valves that have non rising stems that are left open, always back seat fully and then front seat 1/4 turn as this allows immediate proof of the open position as valves fully back seated tend to mechanically freeze, when needed to operate - impossible to tell if open or closed.
Rising stem valves allow visual proof of valve position, certain applications mandate these.
Most old timer boiler men always wanted gate valves installed with the gate in the horizontal position when possible so sediment would not accumulate in the bottom of the gate slot.
Also most codes no longer allow plug type gas shutoff valves.
+Dennis Clos thank for watching& the good points. I was on the submarine "DRUM" last year---lots of valves
Have learned a lot of knowledge, if the manual production of a miniature, what kind of program should be used, thank you！！！！My English level is not good，lalalala
+Wenyan C Thanks for watching-I do not understand your question
hahaha,iam sorry!!I want to make a mini。But will not do
great tips. there's one valve you need to ck twice a year or so it's your water heater pressure valve ..it's very dangerous if it don't work right. it's like a rocket in your basement
+ben mccullough Yes-I do check mine & mess the floor
I prefer ball valves and have replaced most of the globe valves in the house. Primary reason is the globe valves (almost 60 years old) leak like crazy once you touch them! My preference is because a ball valve only needs a 90 degree turn to shut the flow and they're sealed and easily replaced if you can sweat pipe. You don't have to turn ad infinitum and wind up with a wet shirt sleeve from overhead. The ball valves are pretty easy to use while the lever is in-line with the pipe, the flow is on and if it's perpendicular to the pipe, all bets are off. My house has full city pressure ~90 psi and I haven't had any problems with drop-off pressure.
I would never consider plastic pipe, ever! My mother's house is plumbed with plastic and the pressure has to be cut significantly because everything is glued, except for the sprinklers. Taking a shower in her place is like having someone piddling on your head. Tragic.
Outside valves on the hose bibs are another story. I'm a little hesitant about replacing them for two reasons. First, the proximity to concrete walls and second, going through the concrete walls. Sure, I can make extensions but is it worth anything? Probably not so they'll be just fine if they drip when I'm washing the car or watering the grass.
+drcobol2000 Iagree on all accounts. I just put ball valves behind my new wash mach. Hate plastic
Cutaways are always interesting, Thank you.......... O,,,
+Opinionator52 Yes, I enjoy seeing them & making them
Thx man .
+Abdulkader Maqsoud Thanks for watching
what you said @10:50
it was sooooo funny. I kept laughing for a long time
as we got that issue here in Egypt
That gas valve is called a spring valve and they are terribly dangerous because they almost always leak, having largely been supplanted by ball valves.
Those globe valves are more the one usage type, after being installed, the day you need to use them like 10 year later they WILL LEAK all over, time for a ball valve.... ;)
+pierre beaudry So true-they leak at the packing
Every time I need to service a globe valve on something I have control over, they get replaced with quarter turn ball valves with waste ports. It's just courteous to future repair folk. Also they are much easier on the hands and wrists, and nobody is getting younger.
+cougarhunter33 Love those 1/4 turn valves. Thats a great courtacy
like the cut aways...
Thanks
Ball valves ftw
Don't just throw those away. Give them to someone who can teach others, maybe even give them to kids. As a kid I would've rather played with a 3d object than watch a video.
+Andre Gross I shall
"throw this away in 15 minutes"????!?!? that's BRASS.....my grandfather kept a bucket of old brass fittings like that, he'd take them apart so it was all brass.....then, it was either melted down as source material for casting, or turned in for recycling, since brass usually carries decent rates: a bucket worth of "sorted" brass, would be worth ~$1.5 a pound, so a bucket is likely worth $20 or more..... (personally, I'd keep it for casting... ;) )
+Tim Hyatt I scrap all my metals--but the price is really down
While watching this video, I was saying that this is a good training video for work on gate and globe valves. But that went out the window when you made a general statement about young females not being up to date on valves because they sit around texting. I know these are yours vids, but these statements sucks.
NO you do. These statements are TRUE; whether you like it or not. Get over it. "If you cant stand the heat get OUT of the kitchen!"
You have issues
