Safety and Relief Valves Revolutionizing Industry

Mihana Seisakusho produces innovative safety and relief valves unparalleled anywhere in the world.

Conventionally, leakage with valve operation has always been considered to be part and parcel of the nature of valves to the extent that leakage is included in valve standards in Japan and throughout the world. Until now.

Mihana Seisakusho is revolutionizing the way industry looks at valves.

In a safety valve endurance test comprising 100 operations, Mihana Seisakusho’s valve was found by a public agency to have no leakage. Another innovative feature is that the blowing and blow-off phases happen essentially simultaneously.
