Safety Valves and Relief Valves _ MIHANA SEISAKUSHO CO., LTD.
L) Mr. Miyazaki
R) Safety Valve without leakage
Safety valves are essential components in fluid and gas piping systems across oil and gas facilities, marine vessels, railway rolling stock, and food manufacturing lines, ensuring explosion protection, operational safety, and stable supply. Challenging the norm that safety valves must leak, MIHANA has engineered a groundbreaking leak-proof solution.
●Engineered with Unshakable Resolve: The Leak-Free Safety Valve
L) The secret to its leak resistance lies in the ultra-precise flatness achieved through proprietary lapping technology
R) Offering broad compatibility, from high-capacity factory equipment to low-pressure setups
Driven by the belief that "a safety valve designed to protect should not leak when activated," this groundbreaking development challenged long-standing industry norms.
After years of steady experimentation and research, MIHANA finally succeeded in preventing leakage--thanks to its proprietary lapping technology that polishes the valve seat surface to a mirror-like finish. At the time of developing the leak-free safety valve, the company became the first in the industry to undertake a durability test for valve operation. A public institution verified that even after 100 actuations, no leakage occurred.
"When it comes to leak-free safety valves, our company continues to lead the field by far," MIYAZAKI says with unwavering confidence.
●Driving continued business growth through reforms aligned with the time
L) Strategic equipment upgrades to lower manufacturing expenses
R) Safety valves designed for sanitary use, enhancing safety in food production and medical fields
Because safety valves are directly linked to user safety and can require urgent response, the company has launched "Rocket Delivery"--the industry's fastest short-lead-time service powered by cutting-edge facilities.
The sanitary safety valve was also first developed in Japan by MIHANA. To prevent bacterial growth, the inner surface must be polished to a flawless finish--a process made possible by MIHANA's proprietary technology. With strong ambition, the company aims to promote this product widely across both domestic and international food and medical industries.
