Check the rules for this year. I referenced them. If the solenoid meets the requirements in those rules, then it is legal. Namely, COTS part (pass), pressure rating of 125 psi or used with a regulator down to its pressure (spec sheet should have this), Cv of 0.32 (spec sheet), and maximum 1/8 NPT port diameter (see spec sheet again). If it passes all of those requirements, then it passes R78's "allowed" test, which allows it to be used per R75.

If it does not meet the requirements, then it is not legal. But I really don't think those requirements changed from last year. (Be warned, my memory may or may not be faulty--I can't remember if it is faulty or not.)
