SceBelow DN501:5 times the 100°F15 SceDN65~DN200Rating of ANSI Class60 SceUp DN250Max. Operating Pressure180 SceTest pressure should be above 1.5 times than the valve's Max work pressure (100F)(2) Seal Hydrostatic TestThe pressure should be more 1.1 times than working pressure by seal hydrastatic testANSI B 16.34 Section 7.2Valve Size NPSTest pressureTest Time. Scebelow DN501:1 times the 100°F15 SceDN65~DN200Rating of ANSI Class30 Sceabove DN250Max. Operating Pressure60 SceTest pressure should be more 1.5 times than the valve's Max work pressure (100F)180Sce(3) Seal Air TestSeal air leakage test is based on 80PSIG(6kgf/cm2) inert-gas or the air reach the test pressure, then close the valve. after that check the valve whether it is leakage or not.
