no prob. Now that you have got it to turn I would sugest taking that valve out getting a wire brush and some penetrating oil throw the valve in a bowl without the seals and clean it up realy well. Leting the valve asembly soak in the oil over night might not be a bad idea either. After you get it cleaned up and nicely lubed wash it down with rubbing alcohol to remove any oil and throw it back on the PC.

That safety valve CAN NOT be minipulated. It's spring loaded. lol! You have simply cleaned it some. After your run make sure the guts of that valve are nice and clean. That valve can possibly save your life one day, or someone elses if the pressure exceeds 25psi or more.

The safety valve CAN be maniupualted. I just did it. And it was manufactured that way. The main valve is spring-loaded, when it is raised, there is NO pressure being built up. It all exhausts through the holes. (Shown in BOTH pictures.)

When you UNSCREW the valve piece (as shown in the second picture), it adjusts the level the value is opened, thus adjusting of maximum pressure allowed. It's really a simple contraption. Even with the value completely screwed in, it STILL releases steam when it gets to the "danger zone."



Again, as stated three times, the heat on the stove can NOT be adjusted in such a small degree that it will cause the pressure cooker to stay at 15 psi WITHOUT adjusting the valve. Trust me, I fucked with that thing on ALOT of occasions. It either goes up or down.

Thats why I just stated that it worked fine after I adjusted the value.

Thats a good idea about the cleaning you two. Couldn't hurt huh? lol

That's incorrect and highly misleading for new pc users. This post should be removed IMHO for people's well being. By no means should that housing be unscrewed in that manner. The manufacturer made that valve to be screwed down COMPLETELY! All you've done is cleaned out the sealing process enough for it to close up. Horrible information IMHO. Don't tell me there's no setting on a stove that won't regulate and maintain 15psi. I've done a 24 hour run @ 15psi. Dead on and no adjustments to the stoves heat......

Hotnutz how old are you? I am preaty sure that is how the valve was ment to function. It is a simply designed presure valve. If you look at the origional picture of the top of the PC you have 3 things. The handle the guage and the valve.

On a modern PC you ushualy have an emergency release valve a guage and a presure valve. The way the valve on the old PC pictured above works is much like the emergency valve on normal a spring holds the valve shut until a certain PSI and then releases steam. However sence it is the only release on the PC it is also adjustable you can back it off to release steam at a lower PSI. Hence why the valve adjusts and the whole is on the side the more you unscrew it the higher the valve can rase and the more steam can exit. In its origional seting it was snuged fully down meaning it required a very high psi to release presure.

I have only ever seen a valve like that once on a PC it belonged to my now dead great aunt and I was 5 at the time but I remeber her grabing it with a towl and twisting when she was caning jam. I have however e seen many valves like that on old boilers. I believe I have seen a few on air compressors too. If you do a google search on old PCs you can find mention of some of them having twist adjustable presure regulators.

No people with modern PCs should not do this but for this guy with a PC that old yes he should because it is how it was designed to work. :rolleyes:

Why do you keep bumping this thread you posted three times in a row. if you look at the screw in question it should be clear that its function is to regulate pressure. Do you have this pc in qeustion? Have you ever owned or worked with one? The guy said that it worked if he lossend the emerancy relief valve then it wouldnt build pressure up at all.

Don't tell me about bumping threads. Loosening the valve in that fassion is asking to get someone knocked in to the middle of next week my friend! In other words, close the valve by LOWERING it. In the up position it certainly will release steam. Good Lord guys, think before you get someone injured or killed with bad advice........

Do you have this pressure cooker hotnutz or maby the user manual that proves that. This guy has the pressure and can prove that what he did is correct. He even posted that it works when he did his test run. It wont release as much steam in the down possistion thus that is why the pressure builds up to 25psi. When you lossen it it relesse more steam thus 15lbs. I am sure that if you unscrew it all the way no pressure will build up and steam will just pour out. There is a EDIT button there is no reson for you to post three times in a row. POST WHORE. Where is youre proof that the valve that he lossend isnt a pressure control valve? He already tested it so it wont get him killed or hurt.

In the fully up postion your right it is worthless. The force exerted by a spring is = -kx were k is the springs rating and x is the distance the spring is compressed which will be a negative number. By having a valve that you can adjust by twisting you adjust x there by adjusting the force the spring can exert before the plug on the end of the spring reaches the hole and presure is released. When it is snuged all the way down the spring has to reach full compreshion or near full compresion to release steam. Whith the valve twisted all the way open the spring never has to compress at all to release steam. It is exactly like the use of a weight only instead of a weight the force is generated by a spring.

Similar valve designs.

Fuck it Though, believe what you want. I could even make a drawing on how this works but the fact is your not going to believe me and your just going to keep arguing about it. The fact is it works just keep telling your self that I am an idiot and tokey is an idiot for listening to me. It will make you feel smart, he will have a working PC, and I will know that I helped someone, we can all be happy.

Unbelievable! See the rust line on the shaft of the valve? See the rivot going through the valves handle? It SHOULD BE IN THE DOWN POSITION AFTER ALL OF THE AIR HAS ESCAPED AND STEAM IS STEADILY COMMING OUT OF THAT VALVE. THIS ENSURES THAT THERE'S COMPLETE STEAM PRESSURE FOR THE COOKING RUN. ONCE AGAIN!

THE LEVER FOR THE RELEASE VALVE SHOULD BE IN THE DOWN POSITION AFTER YOU'VE AQUIRED A GOOD STEADY STEAMING COMMING FROM THE VALVE. ONCE YOU'VE GOT GOOD AND STEADY STEAM COMMING FROM THE VALVE; CLOSE IT FOR BUILDING PRESSURE TO THE COOKER.

what your saying is true if you want to cook at 25psi. again do you have this pressure cooker? or the user manual to prove that it isnt ajustable. Becouse that guy ajusted and it holds pressure and dosnt explode or kill any one. Where is your proof that it can not be ajusted? I think there is somthing worng with your keyboard half of what you just typed is in cap lock.

If it does not move in to the down postion and seal properly, clean it. You'll need to clean it and get that thing working properly.

See the valve on the left? Same concept as yours, except my cooker has a pressure and air release on the right hand side that screws in and out. Yours is combined. Mine has seperate options. Valve on the left is for pressure safety, valve on the right is for steam release and air release duing the warm up run.

Please note. I have a Masters in Mechanical Engineering from FIT. Besides, there's no collegiate schooling needed for this one. It's rather obvoius if you think first. Any 8th grader would agree with me here.....

Wow, I think I'm sorry I even started this conversation. Hostility!

I'm not worried anymore about it really. It works for me. I know it works and I know it was manufactured to work that way, or they wouldn't have had it screw off so perfectly OR had grips to screw it with.

Of course the valve has to be in the down position. I had it up in the pics for illustration. When its down, it builds up pressure. Then the release valve (combined, as you say) releases at 25 PSI whenver the pressure goes over that much. However, when its slightly unscrewed, it causes a larger hole for air to escape, thus lowering the pressure it takes before it releases steam.

Like I said, I don't really care anymore. Something made in the 1940s will have lots of corrosion and rust on it. I think this thing is in GREAT shape for being so old! And it looks like the seals are brand new!

If you want to try and dig up a manual this thing is called:

BURPEE The Aristocrat Cooker

The company went out of business.

Tokey...

is there any numbers ingraved on the bottom. it's usually a common thing that they number the model of the pc... i would say even back in those days.

if you get that number... have you searched on the net for the instructions? ya might come up with something, and then we can settle this thread once and for all.  :smile:
