2020-3-8 · The safety valves can be tested while operating at low output and throttling the nonreturn or boiler stop valve until the lowest set safety valve relieves. Normal pressure should then be restored by slowly opening the non-return valve. The valve which relieved may then be gagged and the procedure repeated until all valves have been checked.
