When pressurizing an eccentric butterfly valve, pressure is applied only to one side. I’m not aware of the others

Valves should undergo a housing test and a sealing test; the former measures the pressure resistance of the valve body, while the latter evaluates the sealing performance

In the petrochemical standard SH 3518, it refers to the shell test and low-pressure sealing test
