Is this an acceptable location for the Zone Valve Box with only a door separating it from the outlets.  

Chris - would love to hear the background to this question.  It seems entirely straightforward so there must be a backstory.  Reason I am particularly curious is :

1. A report that I have heard of an accreditation person who argues "a door is not a wall", therefore your valve location as shown would NOT be acceptable.

2. A proposal that we’ve made to NFPA 2027 (PI 170, to 5.1.4.6) which should clarify this and of which your example is an argument "For" .
