Body pressure detection

ANSI B 16.34 Section 7.1
Valve size NPS	Test pressure	Test time sce
DN50≥	1:5 times the 100°C F	15second
DN65-200	Rating of AN ST Class	60second
DN250≤	Max. operating pressure	180second
Detect pressure than the maximum working pressure valve 1.5 times higher (100F)

1.Seal hydrostatic test:The pressure should be more 1.1 times than working pressare by seal hydrastatic test.

ANSI B 16.34 Section 7.2
Valve size NPS	Test pressure	Test time sce
DN50≥	1:5 times the 100°C F	15second
DN65-200	Rating of AN ST Class	30second
DN250≤	Max. operating pressure	60second
Detect pressure than the maximum working pressure valve 1.5 times higher (100F)

2.Seal air test: Seal air leakage test is based on 80psig (6kgf/cm^ nin-actiue gas or full filled with air, after dose the valve, then check it is leakage or not by one side of the valve.
