Latest Patents

Hisada holds a patent for a "Butterfly valve with low noise." This invention addresses the issue of noise and cavitation generated in a narrowed flow region by reducing the cavitation that occurs around the valve disc. The design allows for the valve to be applied in fluid flow lines that may contain slurry or foreign particles, making it versatile for high flow rate applications. The butterfly valve features an enlarged section that is symmetrical relative to the center axis, which helps control or suppress noise and cavitation. The inner diameter of this section is more than 1.3 times the inner diameter of the piping, and its length exceeds 0.5 times the inner diameter of the piping.
