numatics/ASCO 411 solenoid
also call HS/LS series miniature solenoid. These miniature solenoid are FR 430 stainless steel structure. The seller Ishop-360 is another guru that build aquarium co2 systems from 2013, he has some good parts available. https://www.ebay.com/itm/2X-New-SS-A...MAAOSw65hexy27 there are some other good stainless steel solenoids too, but rare or higher price than the burkert stainless steel 6011. |

Clippard make single station manifolds for their miniature solenoid valve, the manifolds are chrome plated brass, the one we use is 1/8 npt inlet/outlet verion, part number 15490-5.
And there is interesting history about this particular manifold, the 15490-5. The existence of this manifold all due to the credit of a young highschool kid, his name is Niel. Started from Rex Grigg(also design the Rex Grigg reactor), for many years a lot DIY hobbyists on TPT had been trying to build good co2 system with clippard mouse solenoids because its small size, low flow, high life cycle and extremely low power consumption, but this solenoid can only be connected through the air hose, because there was no 1/8 npt inlet/outlet ports manifold from clippard. Back in 2011-2012 I had to make custom manifold with metal drill and tap, Niel got into the DIY and heard my complain and he sent clippard an email asking for a new manifold, then the 15490-5 was born. Numatics/ASCO also make the single station manifold, in 6061 aluminum, not popular and price double of the clippard 15490-5. Other than that, I don't think the single station stainless steel manifold are available from any major producers, it has to be custom made. It is because there is no point making such single manifold in stainless steel, a stainless steel solenoid with the certain connection type inlet/outlet block is all that is needed, such as a burkert 6011. check Ishop-365's ebay store, he offer stainless steel burkert 6011 too. Anyway, there is a small market for multi-station stainless steel manifold, and I built this system with a 316SS two station manifold from a lucky ebay purchase, see the picture. I believe this two station manifold block is a custom made by Beswick engineering. |

have to use the clippard 15490-5, if you want to connect the miniature solenoids through pipe fittings.
and there are about five major producers making the 10-32 screw mounted type miniature solenoids, they are clippard, numatics/Asco, Kip, Predyne/Gems, SMC. Only the numatics/Asco and SMC make the stainless steel miniature solenoid, SMC miniature is hard to find because not popular. |

Interesting story, I was trying to find one of those 15490-5 in stainless steel but what a shame that they don't exist.
So now with the real question, how bad is gonna be mixing stainless steel tubing with this chrome plated brass, will it affect in the middle/long term? Now I see why clippard solenoids (and related) are not popular in this thread. Yes I saw that solenoid https://www.ebay.com/itm/SS-Burkert-...EAAOSw90le19t5 but is not brand new (minor issue) and is only 42 PSI, my CO2 low is 100 PSI, so in other words if I have to do leak tests, I have to remove the solenoid, that's annoying because you have to check tubing leaks again.

Not as good as 316 stainless steel, but the chrome plated from clippard actually works ok for saltwater environment.
The plated layer is not the shinny type chrome, it is for chemical reaction/corrosive prevention. The clippard manifold can withstand much harsher conditions, same as clippard mouse solenoid. Stainless steel fitting works ok with clippard manifold. Clippard mouse solenoid is not popular here, I think because carbon doser use it? |

I don't see any edit button on my...
it is 1/8 npt ports on the solenoid that we need, not 1/4 npt, because virtually all 1/4 npt solenoids are for higher flow rate, which means higher power consumption, high watts. stainless steel, less than 4 watts and at least 100 psi, these solenoids do exist, but rare. kip solenoid, 3 watts 316 stainless steel, 300 PSI MOPD. (also have another kip solenoid, 1.5watts stainless steel, 500 PSI, no picture) SMC VDW22, 3 watts 316 stainless steel, 105 psi. Burkert 2822, 2 watts 316 stainless steel, 87 psi something I've been searching for years but no luck, it is a parker multimedia solenoid, the spec is 0.5 watts, stainless steel, 100 psi. |

Maybe edit button doesn't let you appear in your browser, I'm using chrome. The closest one seems to ve the SMC VDW22, is that DC 24V or 110V AC? Wow that parker sounds like the perfect solenoid ever built |

built a new set with the APtech stainless steel regulator..
APtech regulator, 0.5 watt burkert multimedia solenoid and a parker HR metering valve. This is my personal set, another APtech, built it back in 2013... |

You made me want to build another system. I have the same reg as yours. Still using the Brooks valve.

whoever got the HPT600 from the auction, congratulation!
here is the HPT600 that I just build Last edited by bettatail; 05/05/2021 at 10:46 AM. |

I never get tired of how sexy custom regulators look.

The good one is what you see in the pictures. got another batch of Concoa 315 and if you need any, let me know. I build co2 systems as another hobby, and selling them to recoup the cost and keep this hobby going, Just like you into beefing up your BMW, the more expensive hobby I have is photography, the camera body alone for these pictures was bought for a price more than the combined profit of selling 20 set of high end co2 systems, lol. I will be away from building high end co2 systems again, for several years, you and flowerfishes take care of others by making more high quality co2 systems.

Question guys... upon killing power to the solenoid, how long does it typically take for the bubbles/CO2 flow to stop? The last couple of builds that I’ve helped people on, they’ve been having issues with the bubbles continuing to flow after power to the solenoid is cut off. Even on my own regulator, it typically takes a least a minute for the bubbles stop. Is that normal, or should bubbles stop immediately once power is cut off to the solenoid? Appreciate your input guys... I’m always trying to learn!

when solenoid is at power off at close position, these is still pressurized co2 between the space from solenoid to the bubble counter, it will take some time for the bubble rate to slow down and stop, normally takes about couple minutes but sometimes as long as 20 minutes depends on the output pressure and size of the cavity/space.
If you want the flow of the co2 passing the bubble counter stop immediately after the solenoid turns off, you can use a three way solenoid, this kind of solenoid not only cuts off co2 flow at the solenoid when it is power off, at the mean time the third port of the solenoid is open, release pressurized co2 between the solenoid and the bubble counter. Need a really good check valve if use with a 3 way solenoid though, you don't want the sudden release of pressure inside the hose that creates water back flow problem. The HPT600 in my previous post has a 3 way clippard mouse solenoid, the top/3rd port is sealed and the solenoid works as a 2 way solenoid, but if I didn't seal the top/third port, this co2 system would release the pressure inside the hose immediately when the solenoid is power off.

Makes sense. Some of these people are transitioning from a CarbonDoser, which runs at typically lower working pressures than our dual stage regulators, so I guess there’s a learning curve to get it properly tuned to the CaRx.
