Reliability standards for high-pressure globe valves for domestic power and chemical plants are currently not actualized. Therefore, it is necessary to secure the reliability of high-pressure valves for domestic plants in order to keep requirement with the international market. However, there are some problems to ensure reliability. First, the cause of the failure should be identified when using the existing valve. It is difficult to identify the cause of the failure because the database has not been established in the domestic market. Second, the reason for the lack of reliability evaluation devices and methods for each product has not been established. Therefore, this study has focused to solve these problems. The failure database in the field was analyzed to identify the failure status and cause. FMEA was conducted based on the analyzed data. It was found that the main cause of the failure was pressure and repeated operation. Accelerated life test method was developed based on actual conditions to ensure reliability of these causes. The Inverse power model for the various accelerated life test models was applied. In order to ensure 500,000 cycles of repeated operation at 180 bar pressure condi tions as actual conditions accelerated life test was conducted as repeated 40,000 cycles at 270 bar pressure. We found that there was no leakage and failure. For this purpose, a jig for repeated test was fabricated and a pressure sensor was attached to the front of each valve, and a monitoring system was installed to confirm the data. As a result of the test, it was sure to guarantee reliability by operating without leakage and failure until the end of 40,000 cycles. This study is based on a database of actual field failures and can be used to develop a reliability assurance test method.
