Section 49-51-10 - Stop valves

(a) Each steam outlet from a boiler, except safety valve and water column connections, shall be fitted with a stop valve located as close as practicable to the boiler.

(b) When a stop valve is so located that water can accumulate, ample drains shall be provided. The drainage shall be piped to a safe location and shall not be discharged on the top of the boiler or its setting.

(c) When boilers provided with manholes are connected to a common steam main, the steam connection from each boiler shall be fitted with two stop valves that have an ample free blow drain between them. The discharge of the drain shall be visible to the operator while manipulating the valves and shall be piped clear of the boiler setting. One of the stop valves shall be an automatic nonreturn valve that is set next to the boiler, and the second valve shall be the outside-screw-and-yoke type and shall meet the requirements of sections I, IV, and VIII of the ASME code. All piping, fittings, and valves shall meet the requirements of the current code of construction.
