The test gag is used for: - to perform pressure tests in a system without dismantling of the safety valve - the individual adjustment of safety valves installed in the same system Options After testing the test gag must be removed because otherwise the safety valve cannot protect the system against unallowable overpressure! 09/04 LWN 481.01-E
