Re: Al's Annual Inspection Thread 2015
Another Q&A A welcomed clarification of the solenoid pressure rating rule. Pretty much any industrial valve with a rated working pressure over 100 psi should meet this.
R446
Quote:
Q. R66(D), a solenoid valve "rated for a maximum working pressure that is less than 125 psi" versus a relief valve "set to a lower pressure than the maximum pressure rating". According to the manufacturers we have contacted and NFPA definitions MWP and MPR are 2 unrelated requirements. A valve is safe up to its MPR but only rated to "work" (the solenoid would actuate the valve normally) at it's MWP. If the MPR is >125 (ours is 215) is it acceptable without additional relief? Our MWP is 115.

A. Thank you for the question. This is legal, and the language will be updated in the Game Manual in Team Update 2015-03-17 to be consistent with this answer.
