What do you want to use the pressure relief valve for?

If this is to stop excessive build up of pressure during normal operation of your generator, then you might be better advised to incorporate a pressure switch into your electrical control circuit to shut the generator off in the event of high pressure build up.

If this is to let gases escape, in the event of a blowback, then there are a number of solutions to same posted on the forum. In this case, do a search of the forum for blow off valves.

Did you find what you were looking for? I didn't ask when I was at the same point but I took a stainless fender washer, drew a circle around it on the top of my bubbler cap, drilled as large of holes around the inside of the circle as I could, and one 1/4" hole in the center, ran a long ss screw through the washer, a rubber disc, the cap, then put a ss spring under the cap, a washer and a nut at the bottom. This is on my resevior/bubbler and Im sure it will work, but I haven't had a back fire so it isn't proven, I'm going just on instinct. Let us know what you do and how it works. john.

If your generator produces so much HHO that you need a pressure relief valve, I sure would like to see the design.

The fastest way to create a quick pressure relief valve, blowoff valve, or anything of the sort is to drill a hole about 1/4" or larger and slap a piece of duct tape over it. Problem solved! I've done it before and even tested a few times, it's a win-win scenario Big Grin

-DNX exhaust
-Injen Short-Ram Intake (SRI)

I just use vaseline for the seal for the hoses. That way if they build up too much pressure, the hoses will just slip off with little problem-hasn't happened yet in over 1 year of running. The vacum from the engine is usually enough to keep everything going.

Go to http://www.hhoglabs.com

Look at the product called "HHOG II EPD v2." This opens at 10-15 psi. Its main purpose is to relieve pressure if there is a flashback and then immediately reseal so hho continues to flow. I built one of these for less than $5. Check out the videos of it on youtube.
