Re: Electrical propane shut off valve

Now you mention it, all I could find in the ABYC code is that the regulator must include a way of isolating one cylinder from the other - you can't just t them before the gauge - which that regulator includes. Guess the design then necessitates two gauges to be able to leak check it whichever channel is selected.

Why don't they put the gauge after the valve and thus save a guage? Who knows? So you can see if both tanks have gas in with just one selected?

The handy thing with 2 gauges is that if they both drop, you know the leak is downstream, whereas if one drops, the leak is between the gauge and the tank.

Re: Electrical propane shut off valve

Any cylinder can be easily isolated from the other because they all have their own valves - to leak test close one and open the other. That is the way a dual tank system is usually, a pigtail from each tank and then into the reg or solenoid depending where it is located.

Re: Electrical propane shut off valve

Tell ABYC that

A-1.7.4 In addition to the valve required at the
cylinder, a multiple cylinder system shall be provided with
a shut-off valve, or automatic check valve, at the cylinder
manifold so that each cylinder can be isolated from
pressure feedback from other cylinders.

Re: Electrical propane shut off valve

"A shut off valve, or automatic check valve, at the cylinder manifold....."

A shut off valve can be manual - the "or" gives you the option.

Re: Electrical propane shut off valve

The "cylinder manifold" in this case, means the T, I think. The dictionary definition of manifold being :

"A pipe or chamber having multiple apertures for making connections."

The regime in that pic has neither an automatic valve, nor a shut off valve, at the manifold / T.

One regulator is fine but two electric solenoids would be preferred as when you are running the heater the stove would be seeing propane pressure. If the stove had a leak then you could have issues. Both lines need to terminate inside the propane locker. No tees in the boat. I find with manual vlaves people just don't use them. A galley mounted 12V switch or breaker, with a bright RED indicator light, is tough for folks to forget or miss.

I personally prefer solenoids in the high pressure side, right after the tank, so in that case you would need two regulators too. Having seen low pressure regulators leak is why I prefer my solenoid on the high pressure or tank side of regulator..

My favorite solenoids are made by AFC and I install a lot of the model 151. Not a big fan of the low pressure solenoids as I don't find them nearly as reliable over the long haul. The AFC 151 can be found for pretty short money too. This is the SAME valve Fireboy-Xintex relabels and sells for more money.... Never had or seen an AFC 151 fail. everything can but in relation to the "low pressure" solenoids I find the AFC valves to be far more reliable....
