A structure that makes it difficult for foreign objects to clog or adhere in the fluid, and a design that reduces the load on the seat compared to a ball valve, ensuring stable valve operation.
The segment ball valve is a stainless steel valve with a 90-degree opening and closing that features an eccentric structure with excellent sealing properties, helping to reduce lifecycle costs. We offer manual, high-torque electric drive, and air cylinder drive options. Sizes are available up to 300A.

Company information
Our company is a young entity established on August 1, 2024, as a spin-off from Protearial Co., Ltd.'s piping equipment business. However, its roots can be traced back to Tobata Casting Co., Ltd., which was founded in 1910. When we launched our first product that same year, we cast it with the wish for "greater strength, smoother surfaces, and more beautiful curves," resulting in the "Hyoutan" mark. For over 100 years, we have continued to produce cast products under the testament of tradition and trust. Currently, we manufacture and sell not only fittings and valves but also sealed diaphragm expansion tanks, semiconductor flow control devices, and cold water supply equipment. In addition to these piping equipment products and our fine flow products under the "SAM" and "Aera" brands, we take pride in our comprehensive capabilities that improve on-site operations through our technical expertise, support systems, and quality control measures, which meet societal needs such as efficient energy use and the realization of a safe and secure society. Although we are a young company, we will continue to cherish tradition while providing new value to the industry in line with customer needs and market changes. We are committed to making efforts to meet our customers' expectations, and we look forward to your continued support.
