hey there all! i have some questions about the regulator/solenoid/needle valve/ whatever else i missed. how do all these parts connect and where can i find the connections? i'm building a pressurized co2 system for the first time and need some guidance. i have just purchased a dual stage harris 8700 regulator on ebay for like 23 bucks. heres the link eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices where do i go from here???
The regulator and various parts will connect in the order you have listed them above. Regulator outlet --> Solenoid --> Needle valve --> Bubble counter(inline or needle valve mounted). The parts to connect all these together will be highly dependent on which solenoid, needle valve, and bubble counter you choose. Did you have any ideas about which of these you'd like to use?
Ok kewl thanks. I would like yo use what is required to have a good quality system while saving cash. Which solenoid, needle valve should a I go with(brand)? And where can I find them? Does home depot carry the connections?
you will probably be better off checking out a local welding supply store to order parts. this is a long read, but should be very helpful if you are building Dual Stage Regulators - Aquarium Plants
Since you are in the US, I'd give Orlando over at GLA a call. He'll get you set up right with all the stuff you'll need. As for needle valve/solenoid choices, I'd probably go with a Fabco NV-55, and maybe a burkert solenoid. Again, Orlando should be able to get you whatever you need.
I suppose that you have gathered by now that your Harris 8700 series regulator is not suitable for our use. Its pressure range is much too high. It is from 0 to 4000 psi. We use regulators that have 0 to 30, 0 to 60, 0 to 100 and 0 to 200 psi low pressure gauges. Usually their output is 50% to 75% of this gauge. This is your Harris 8700
yeah i just gave it to an employee at airgas lol he was pretty excited. i got an aquatek regulator with needle valve bubblecounter and solenoid so far its been running really well
