Need Solenoid Valve

Interesting challenge. I am familiar with "industrial size" ammonia solenoid valves, quite a bit larger than this. I presume that the plastics and elastomers are the sticking points for this example.

Carbon steel, stainless steel, Teflon^®, and neoprene are NH₃ compatible; most copper alloys are not. I doubt that a Teflon^® body could handle the possible pressures, but am unsure (and might not be available even as a custom design).

This doesn't fully answer your question, but maybe it can be a start. Best of luck. Such a valve would be handy for sending samples to an ammonia detector, for instance. If I can find anything, I'll post further.

Thanks Tornado

I have 4 companies that come to mind.

1) Ingersoll Rand, ARO division. They make many designs, within these designs, there are many more variations. www.ingersollrandproducts.com

2) Clippard pneumatics is involved with small designs. www.clippard.com

3) Asco red hat valves. They are older than dirt, and seem to cover many variables. www.ascovalve.com

4) Whitey valves, by Swagelok. I have some air operated designs that work with 2500 PSI, and have teflon seals and 316 stainless steel hard parts. www.swagelok.com/products/valves

Good luck.

Hello NSS. Ammonia is still used in commercial refrigeration. You can try the refrigeration control companies like Danfos, Emmerson Climate, Alco, etc (disclaimer). In fact I believe they recently sent a tank of ammonia to the ISS.

Good Luck!
