SEDELON passed the fugitive emission test successfully for 8inch 900LB gate valve with total 1500cycles at high temperature 300℃. We are very satisfied about the test result and very excited to get the ISO 15848-1 Fugitive Emission Certificate.
Various valves cannot be judged by conventional water pressure and air pressure tests, and need more scientific methods and more sophisticated instruments to detect small external leakage. Such small leakage to the external environment is called micro-leakage.
ISO 15848-1 fugitive emission certificate is right for this measurement, test and qualification procedures of micro-leakage valves.
The coverage of our fugitive emission certificate is below.
GATE VALVES
150LB:2’’-42’’
300LB:2’’-38’’
600LB:2’’-28’’
900LB:2’’-24’’
