In a high pressure system (>15 PSIG), ASME Boiler & PV Code, Section I, is usually an accepted Standard, and it requires, for any boiler having a man-hole opening, two stop valves with a free-blow drain between them (PG-58.3.2). Usually, the valve closest to the boiler drum will be a combination stop & non-return.
