Double Hose Outlet Connection (Hydrant) is mandatory to have a main control valve or a double independent 2.5" gate valve will solve it?

Per NFPA 24 - 2016  - a control valve shall be installed in each hydrant connection.

I´m installing a hydrant similar to a pump outlet connection, because I cannot install underground pipe due to some design restrictions.

The question is, do i require a main control valve for that hydrant ?  or applying I do not require the main hydrant control valve replacing with independent 2.5 inch gate valves ?


 A control valve shall be installed in each hydrant connection. Valves required by shall be installed within 20 ft (6.1 m) of the hydrant. Valves shall be clearly identified and kept free of obstructions. Where valves cannot be located in accordance with, valve locations shall be permitted where approved by the AHJ.* The number, size, and arrangement of outlets; the size of the main valve opening; and the size of the barrel shall be suitable for the protection to be provided and shall be approved by the AHJ. Independent gate valves on 21⁄2 in. (65 mm) outlets shall be permitted.
