No leaks even after 100 operational tests.
Conventional safety valves are expected to leak when activated, and this has been considered an unavoidable phenomenon, with permissible leak limits even being defined in domestic and international standards.
To overcome these challenges, Mihana Manufacturing developed a special technology and undertook the industry's first "safety valve operation durability test." After 100 operation tests, it was certified by a public institution that there were absolutely no issues, and we were able to receive a certificate of authenticity. Furthermore, it is a groundbreaking product in that the start and release of the airflow are almost simultaneous.
