Pressure is not required to create a high pressure, the ball is forced downstream, flexing the downstream seat and creating a seal. The upstream seat also flexes with the ball movement and maintains a Information About Swagelok Process Ball 2 Features.
rated pressure if less than 1000 psig (69 bar) is performed to a requirement of no detectable leakage with a liquid leak detector. Shell testing at 1.5 times the maximum working pressure is performed on CE-marked 67 and 68 series valves.
