Propane Supply Switch Design

Jackm · 10-09-2009, 09:16 PM

I noticed that the new Winnebago Via (Sprinter chassis Class A) has a propane supply cut-off switch on the dash. This would be a nice feature to have when gassing up or entering areas that have mandatory propane supply regulations.

I would assume that Winnebago uses some kind of electric flow switch to control the propane supply. Has anyone ever seen or had any experience with this type of system? I would be grateful since I might try to install a similar system in our motorhome.

jack, it's my understanding that if the propane leak detector is not on then the gas supply is not on either. Perhaps you could check this out and if I'm right then install a switch to control the propane detector.

On my rig (2004 Winnebago Brave), I don't have any automated propane supply shut-off capabilities. However, there may be some commercially available solenoid valves that can be used for propane. Thanks for the fast feedback.

jack, look for a solenoid valve that can go inline after the regulator at the tank. The pressure after the regulator is about .5 psi. I am sure one is available just don't know where to tell you to look.

Found one at http:////www.westmarine.com/webapp/w...1/10001/308963

Thanks again.

If you have been operating the refrigerator, water heater or furnace while travleing and just shut off the gas flow; be aware that you will need to turn offf these appliances before pulling up to take on fuel. Otherwise they will be trying to ignite; producing a high voltage sparking that could be as bad as an open flame itself.

My 95 American Eagle has a system by CCI Controls, (800-521-5228). It came with the coach and works great. It is a model 7719 Gas Leak Detector with valve. I am sure that it has long been updated. It works great, will shut down system if it detects a leak.

Mike,

It's too bad the manufacturers don't emphasize this point a little better. I've never shut off the fridge when turning off the propane. I will now. Thanks much.

CCI Controls, who made propane detectors that had the ability to shut off a propane valve, is no longer in business. You can still buy their propane valves at places like PPL Motorhomes Parts, though.

Gary - I think I read somewhere that the propane valves that worked with the CCI detectors were 9 VDC units because that was the voltage put out by the detectors. I don't know if a 9VDC valve would be damaged or not if hooked up to 12 VDC. I have never seen the specs on these valves. We had this system on a previous coach and it was great. We could turn the propane off at the detector and turn the fridge off before entering the gas stations. After fueling up and hitting the road it was easy to turn them on again.
