The directly operated coaxial MK valve and the externally operated VMK valve from müller co-ax gmbh exceed the strict requirements of the flame resistance test according to DIN EN ISO 19921. This standard defines test standards for determining the flame resistance of materials used in the marine and offshore industries. The flame resistance test is critical for all vessels, as it ensures that the installed valves operate reliably even in the event of a fire and prevents dangerous situations such as explosions or the release of harmful substances. This ensures the high safety standards in the marine industry.
During the test, the valves were exposed to flames at a temperature of 800°C for 30 minutes while water circulated inside the valve at a pressure of 5 bar. The water temperature at the inlet was 80°C and a maximum of 85°C at the outlet. The flames were generated by gas burners in accordance with DIN EN ISO 19921.
The testing institute, Dr. Ing. T. Bäumer GmbH, certified that the valve remained completely sealed to the outside during and after the test, and no seat leakage was detected.
These successes underscore our commitment to quality and safety. Our valves are designed to function reliably even under extreme conditions.
