24V Solenoids

[BryceKarlins]

So, during a post-build season rules read, and I realized that as per R18, the Motors & Actuators chart, that the rules don’t allow solenoids that take over 12 volts!

Electrical solenoid actuators, no greater than 1 in. stroke and rated electrical input power no greater than 10 watts (W) continuous duty at 12 volts (VDC)

Not only have we been using 24V solenoids to no issue for a couple years now, theres a 24 volt jumper on the PCM!

Can someone tell me I’m suffering from pre-competition paranoia?

[dradel]

yep just paranoia.

The rule you quoted is talking about electric solenoid actuators, not pneumatic solenoid valves. 24V solenoid valves are still legal.

Don’t worry, 24V pneumatic solenoids are fine.

There’s a distinction between an electric solenoid and a (pneumatic) solenoid valve.

R66 is what concerned solenoid valves.

C. Solenoid valves with a maximum 1/8 in. NPT port diameter,
D. Solenoid valves that are rated for a maximum working pressure that is less than 125 psi rating mandated above are
permitted, however if employed, an additional pressure relief valve must be added to the low pressure side of the main
regulator. The additional relief valve must be set to a lower pressure than the maximum pressure rating for the solenoid
valve,

This is where I’d remind you to switch the PCM jumper to 24V, but you already know about that it seems. :rolleyes:
