NFPA 24, Section 22.214.171.124 (2016 Edition), states that control valve shall be installed in each hydrant connection.
What is the purpose of this control valve, other than facilitating maintenance?
Would this be considered a "control valve" per NFPA 24 3.3.3, and does this have to be a post-indicating type valve?
Common hydrant arrangement for illustration purposes.
Based on my limited understanding, this control valve is just a post-indicator valve/isolation valve which is for shutoff when there is an impairment downstream. I'm trying to get a better understanding of its purpose. Thanks in advance.
