open under no flow condition to demonstrate that the assembly is
working smoothly.
Each valves
are hydrostatically tested at the place of manufacture to the pressures
specified (Shell test at 1.5 times the working pressure and Seat test
at 1.1 times the working pressure)before they are packed for delivery.
