Abstract :
A measurement principle for quantitative control valve seat leakage classification, in accordance with ANSI/FCI 70-2 and IEC 60534-4, based on the acoustic emission measurement in the ultrasonic range is presented. The advantage of this method is that the leakage test can be performed on-site without having to disassemble the valve. The valve has to be closed for this test. If the valve is occasionally closed under normal operating conditions, the test can also be done on-line.
