View Full Version : Solenoid valve for bed lift

I had noticed my 110v air compressor running more frequently and today it was taking a long time to come to pressure. After looking for leaks I found that the solenoid valve for the bed lift air ram was leaking air. I ended up cutting the air tubing and plugging that to stop the air leak. Now I need to find another solenoid. It is a SMC NVK3120 0-100psi 12VDC. Does anyone know where to get one of these online? I'm in Moab now and it will be next month before I get down to Phoenix area. It's not a rush, there's nothing under the bed we will need anytime soon.
Thanks.

Is that a "magic fingers" bed?;

The inventor has since passed so parts may be hard to find!

Haha! No, just the solenoid valve for the air ram to lift the bed to access the storage space under it.

Forest,

You might try googling the part number; if that doesn't work google the manufacturer's web page. If that fails, call Newell.

hi forest. SMC is very good about helping you if you call them. you can order direct from them as well. i got a rebuild kit for the ram that pushes my bay fridge/freezer in and out from them. that ram was an smc one.

it is a common valve and appears to be about 45 bucks. but there are many configurations.

Thanks, I did google the part number and found some on ebay but they are 24vdc and I need 12vdc. I even found that 0-0.7Kpa is 0-100 psi!
I guess I'll call SMC and order from them or from Newell. It's not a rush job, just something I want to get done so that I don't forget about it.
I may even take it apart and see if I can clean it when I get a chance. The main thing was to reduce the load on the air compressor.

Forest,
At some point after your coach was built Newell changed the bed lift to a 12V motorized ram. This may be a cheaper alternative to an air ram and would get rid of one source of air leaks. Might be worth doing a cost analysis.
