Automated Rig Piping review

Your planning to sell them with position control capability also?

If I was doing it again I would put a 3pc ball valve on the outlet of each pump for flow control and everything else would be butterfly.

Why not butterfly on the pumps too? Better linearity (if that's a word ) than a ball valve.

Yea thats true.

I used a NPT 3pc ball valve and a TC 3pc ball valve to make 2x NPT to TC ball valves. I liked this setup so I pictured sticking with it (didn't want to modify the pump). A butterfly valve would work too.

Allan, Can I see what valve you have built?

I backed away from doing motorized valves and went with TriClamps, so I doubt it's much help to you. My work in progress is here:

I love the brewery! great job so far

I went with 8 motorized valves. They are a little custom from the manufacturer. Just 2NM force over 1nm that people normally get. I didnt want to deal with stuck valves. But at the moment im working on integrating actuators with TC butterfly valves. When I get the stand completed I will post pictures of all the crazy amount of TCs and stainless I have.

Thanks. Motorized TC butterfly would be my ideal. I'd love to see what you come up with eventually.

Ok, any progress? Planning my valve purchases for the new system!

No progress on the valves, I have purchased 3 different ones all 1 inch tri. I own the economy, 3 peice, and butterfly and they are all really hard to turn. definitely over 10nm. But don't lose faith I am working on them diligently along with moving this week.

I think a lot of my problems are because I cant seem to find out how much force it takes to turn this valve. Not that I cant do the math but their are zero specs out their.

Im eating my words, after searching for a week or so I finally found them. The butterfly valve is saying 13 ft lbs "max" torque, the actuator I am sourcing is 7.3 ft lbs. Should work.

Cool, keep me posted. I'll figure out my layout for plumbing in the next few weeks for the new build

Yeah i will. Their are a lot of factors that will determine how far I take this. Most of them come down to Feasibility. I still need the actuator in hand from china, CAD up the body mount and get them manufactured.

Even better is I found an actuator through my supplier that can accept a yellow 0-10V control signal wire to control the valve’s open angle. So cross your fingers that 10nm will open these valves. This is were I may need the help of my engineering friends to make this user friendly. If we cant get them to do it sanitary, I can still source these valves in.

Tag me as very interested, I'm building a system with a raspberry pi backend.

Let me know!

Doug, I may need your help with the raspberry Pi, I am somewhat over my head. This is my build :https://www.homebrewtalk.com/f51/my-insane-25-gal-100-percent-hard-plumbed-tri-clover-automated-tippy-build-409516/
