Every DBB and SBB valves is factory tested hydrostatically
to a requirement of zero visible leakage. A shell test is
performed at 1.5X maximum rated working pressure and
a seat test is performed at 1.1X maximum rated working
pressure in accordance to API 598 and BS EN 12266-1. A
low pressure gas seat test is performed in accordance
with API 598 and BS EN 12266-1
