All American Sterilizer control valve, model 65 or 65K?

Hey folks, Not sure where to post this. But I'm going to convert my PCs after running the rocker weight with added weight to run 20psi. I want to be able to run longer cycles without worrying about running dry, less noise, and no more stinking up the house!
I'm going too replace the black rubber blow out plugs with the red ones, even though my 921 does pull vacuum on cool down with the black one. My 930 doesn't pull vacuum as well as the 921 does, so I guess the plug is why. It hasn't been an issue though.
Now, there seem to be 2 control valves available online, the 65 and the apparently newer 65K.
Does anyone have experience with both valves? I like the look of the older style better, but function > form, so if the new one is better I would grab those. Which one should I get?
Older model 65:

Newer 65K:
 Where does the new one vent from? I see that the old one has 4 holes around the top, but I don't see that at all on the new one.
All pictures of the old model 65 valve look like it screws into an adapter before screwing into the lid? Like this pic:

I can't seem to find this part. Is it included with the valve? Is it required or is it just a spacer? Does the 65K not need this?

It looks like the new one vents from the bottom, those slits above the threads. I could be wrong of course, but that's what it looks like to me.

I just got a 75x and mine is like the 65k but it's silver. The matsc is correct, they are under the little hood-looking thing.
As for which one you should get, I have no basis for comparison but I would assume the newer is better.

I noticed that on the pics you posted. Nice piece of equipment bro! I also noticed that your sterilizer has that same fitting between the valve and the lid that the older models are always pictured with. The valves for sale online don't look like they come with that. I'm gonna have to order the valve and see if it comes with it. If not, I'm sure something similar can be found in a hardware store.
How you liking that 75X?

I have only used it once so far but tomorrow and Monday I plan on using it for bag, agar and some jars. But I like it so far. The instruction manual that came with it sort of conflicts with some of the reading I've done. The manual says to open the valve once your time is up. But most people say to let it sit until it reaches about 0 psi.
What do you think about that?

The newer control valves suck!! Don't buy them. The rubber used for seating the valve comes off easily and is a pain in the ass. I like the older ones. They are more reliable.

Perhaps its because they expect people to be steriling equipment which isn't vulnerable to sudden changes in pressure, dental, medical, etc. This is pretty much what it states on their website. Sudden pressure release is going to boil your agar out of the container and increase the chances of your bags bursting.

What he said. Think about it. At atmospheric pressure, water boils at or below 100C (depending on elevation). At 15 PSI its 121.
So, your 121C liquid agar is suddenly dropped to room pressure, its suddenly way past its boiling point. It flash boils, and you end up with a sticky nasty mess.
This is also what happens in my lab when the new interns forget to change the setting on the autoclave to wet-cycle. Its never fun.

Gotcha. Luckily I did it right by leaving the bags to sit as the sterilizer cooked. And now I'll avoid at least one ill-fated mistake. Thanks.

Thanks! This is exactly the info I need! I'll order the older model. Hopefully the site listing them actually has them and are not shipping the new models instead.

Yeah you deffinitley did the right thing by not popping the valve to release pressure. Also, after cool down the sterilizer should pull a vacuum after pressure drops to 0. So for unsealed bags or any vessels with loose lids it would be best to break the vacuum in front of your flow hood so no nasties get sucked in.

A lot of us add a micron filter with a ball valve by installing a "T". This way you don't have to lug the damn cooker everywhere.

I need a fast answer. My manual to my 75x says to let the valve stay open for 5 minutes to let air escape. Then to close it until it reaches 17 psi. The once it's there, open it again for 3 to 5 minutes. After that it tells you to start the clock.
Will this be a bad idea ?
What should I do?

I think that is for when sterilizing tools and shit like that. You would not want to do that for mycology work like sterilizing grain bags or agar etc. Would probably cause bags to blow out, agar to boil over, filter patches to be blown off jars lids etc.

Their protocol is for medical instrument sterilization.....Scalpels and such.
For you a protocol.....
Pack sterilizer leaving space between each item.
Close and tighten wing nuts and open control valve.
Turn on high. Dial all the way clockwise.
Once the cooker starts sputtering steam (30-45 minutes. If very full possibly 1 hr.) count 10 min then shut control valve.
Allow the sterilizer to get to temperature then turn temp dial counterclockwise until the light shuts off.
Set your timer for needed time according to density of fill.
Cook
Turn off and let cool.
Open control valve slowly after a minimum of 45mins has passed in front of a hood, in a clean room or by means of an inline hepa filter.

Well, FWIW, I ordered from somewhere that looked like they were selling the old style still. I received the new 65K model.
I guess the old version is not available anymore. 
I ran my 921 with the 65k valve and made some agar and SD-H2O.
Was nice having the cooker running silently. Pretty easy operation.
The pathway through the sterilizer valve must be larger than the vent nipple that originally came with the 921. Because I usually let steam blast out of the vent until the gauge reads 2-3psi before applying the weight. I had steam blasting out from the control valve but no pressure was building when there would have normally been a couple psi. So I flipped the valve closed and kept the heat cranked to max. Pressure built up quickly. Once it hit 10psi, I backed the heat down to halfway, pressure continued to build(slower) and I continued backing off the heat once 15 psi was reached. Eventually I had the gas just a cunt hair up from the lowest possible setting maintaining 20psi.

Less water used, less gas used, silent operation! All wins!
I did kinda have to baby it though to keep pressure where I wanted it. Being the first time using this configuration I never left the cooker out of my sight. When the gas was turned all the way down pressure dropped 1-2 psi and I had to give it a little gas to bring it back up. And then when it went to like 22psi I backed off a bit again, etc. My cookers are no longer set and forgettable at 20psi like they were with the vent pipe\weight combo. I suppose after a run or two I will find that new perfect sweet spot on the gas range. But I'm not sure I am as comfortable leaving the cooker running while I watch a movie in the next room anymore. Fuck, before I would go take a nap and set alarms to wake me up when I was doing late night cooks. LoL
