Safety Valve Sizing. The sizing of Safety Valves is particularly important. Valves that are undersized will not be able to discharge the maximum capacity at the specified overpressure and as a consequence the system pressure will not drop but continue to rise.; Valves that are oversized will not achieve the fully open state.
