the sprinkler solenoids are rated for 150 psi

150PSI gas?
Sprinkler valves are generally only rated for liquids.

P.S. It's the valve portion, not the solenoid that's rated for pressure

Sorry I meant the valve not the solenoid.

I'm not sure if it was rated for gas and liquid but i know it was 150PSI.

Either way it should have the same chance of failing regardless of Air/Liquid. It's just that if it fails with air the results will be much worse.

Compressed air has more energy than compressed liquid. You want to use a valve that's specifically rated for compressed air.

Compressed gas does have more energy than compressed liquid, but the force exerted on the valve is the same. Pressure is pressure, air just compresses significantly more than liquid so its potential energy under pressure is much greater.

precisely. That's the part of this discussion that convinced me (and my teammates) that continuing to use a sprinkler valve was a Bad Idea™.
