Boilers operating over 100 PSI require 2 bottom blow valves. One valve can be quick opening and one valve must be slow opening. In that case the quick opening valve should be next to the boiler and opened last and closed first. Over 125 PSI the valve and piping must be extra-heavy.
: can anyone tell me what the asme requires for bottomblow valves and when
: is two valves required.
