Mihana Seisakusho manufactures epoch-making safety valves and relief valves that are literally the first products of their kind in the world.
With conventional safety valves, a certain amount of leakage is considered unavoidable during operation, which is why Japanese and overseas standards exist to specify permissible leakage levels.
In order to overthrow conventional wisdom, Mihana developed a special technology with which it challenged the “Safety Valve Operation Endurance Test”. As a result of this test undertaken by a public organization, the company was awarded a certificate confirming that its safety valve produced absolutely no leakage even after being put through 100 operating cycles.
Moreover, Mihana’s valve products are epoch making in that the “blow” and “blow off” phases occur almost simultaneously.
