MIHANA SAFETY VALVES

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.

Safety and relief valves revolutionizing industry: -

●Patent received: -

ISO 9001 certified production plant

Approved for high-pressure gas facility testing and manufacturing

Certified to use the Japanese Industrial Standards (JIS) mark

Chinese Safety Quality License

●Applications: -

The Mihana Seisakusho safety valve is used in a wide range of applications including such industrial devices as compressors and boilers, automobiles and containers, food processing equipment and medical devices. It is also used in the such industries as electrical power, petrochemicals, manufacturing and atomic energy.

9- Safety Valves without Front Leakage

Mihana Seisakusho produces their safety valves using an advanced lapping (grinding) technology that eliminates front leakage (during the blow phase). No leakage was found even in tests with 100 repeat operations using a Mihana Seisakusho test device.

●No start-to-leak function: -

Finally Mihana satisfies the needs of the safety valve market by providing "no start-to leak" vales. Its valves operate simultaneously two hobs; beginning to blow and bursting out.

●An advanced lapping technology: -

Due to its exclusive lapping technology, Mihana is capable to develop an areal contact at its valve seat, instead of a conventional liner contact.
