Ball Valve | Manual High Pressure 3-Way Valve 'BK3 Series' / Carbon Steel & SUS

Ball Valve | Manual High Pressure 3-Way Valve 'BK3 Series' / Carbon Steel & SUS

High-pressure three-way ball valve with a maximum operating pressure of 50 MPa, compatible with up to 1.1/2 inches, full bore structure / carbon steel and stainless steel.

The manual high-pressure full bore ball valve "BK3 Series" is designed for use under high pressure and is a diverging type high-pressure three-way ball valve that branches fluid in two directions. Its full bore structure results in extremely low fluid resistance, and its compact design excels in piping layout considerations. The "BK3 Series" has received positive feedback for its ability to be modified while utilizing existing piping as is. It is ideal for hydraulic applications in construction machinery, high-viscosity fluids such as polyurethane foam and paint in automotive manufacturing lines, high-pressure water cleaning, and inks in printing equipment. We can respond to urgent requests with short lead times. <Features> - Maximum operating pressure: 50.0 MPa (*1) - Full bore structure - Diverging type three-way - Can be used as an automatic control valve in combination with pneumatic or electric actuators - Materials available in carbon steel and stainless steel - Options include limit switches, solenoid valves, locking mechanisms, and explosion-proof specifications - Short lead time for standard products (*1: Varies depending on valve size, material, and operating conditions) Please feel free to consult with us. Catalog downloads are also available.

Carbon Steel for Mechanical Structures "SC Steel Plate"

Carbon Steel for Mechanical Structures "SC Steel Plate"

Excellent quality! Steel plates manufactured under consistent quality and process management from raw materials to finished products.

"SC steel plates" are carbon steel plates for mechanical structures that are typically produced through hot rolling and further processed with forging, cutting, and heat treatment. They are manufactured in electric furnaces suitable for producing high-quality steel, ensuring uniformity in composition. With consistent quality control and process management from raw materials to finished products, we can provide a stable supply of high-quality SC steel plates. [Features] ■ Excellent quality ■ Superior toughness ■ Sound internal quality ■ Short delivery times For more details, please refer to the catalog or feel free to contact us.

Lost wax (precision casting) Material: Carbon steel S25C

Lost wax (precision casting) Material: Carbon steel S25C

We handle a variety of products that meet the needs of our customers, such as impellers (SCS13) and heat-resistant steel (SCH22)!

Our company handles "lost wax products," characterized by a unique mold manufacturing method and casting technique. In response to supply uncertainties, including recent natural disasters, we will establish stable supply sources not only within Japan but also by partnering with manufacturers in South Korea. Due to the special mold manufacturing and casting methods, molten metal is poured into highly permeable molds heated to approximately 1,000 degrees, improving the flow conditions of the metal, which allows for a wide range of metal types to be selected. Additionally, the mold structure varies from simple two-part molds to complex split molds made of fine components, and no draft angle is required. **Features** - Allows for free design of complex internal shapes that are difficult to machine, as well as three-dimensional curved surfaces. - Enables the design and production of integrated structures from multiple parts that were previously assembled after processing. - Capable of producing items ranging from a few grams to large pieces weighing around 40 kg, depending on conditions. - Depending on the product shape and weight, we can accommodate orders from a few pieces to tens of thousands per lot. *For more details, please download the PDF or contact us.*

Strengthening Manual for Screws (Vol. 18) What is carbon steel?

Strengthening Manual for Screws (Vol. 18) What is carbon steel?

Introducing the numerical values associated with SWCH in a blog format!

The number that follows SWCH refers to the carbon content, which typically ranges from 8 to 18, but this is expressed as a value 100 times the actual content. In other words, if it is 8, the carbon content is 0.08%. These are low carbon steels, and in terms of the strength classification that will be mentioned later, they are used to make screws of the so-called low strength category, such as 4.8. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.
