"Friction Stir Welding" is a technique that joins base materials by rubbing them together at high speed, softening the materials due to the friction heat generated while simultaneously applying pressure to achieve the joint. It eliminates the need for consumables such as welding rods and flux, reducing labor costs. No heat source other than friction heat is required, resulting in high energy efficiency. Additionally, it allows for a reduction in material and processing costs compared to machining from solid blocks, and by minimizing the weight of the material, it can improve yield rates. [Features] ■ Achieves joint strength equivalent to the base material through individual jointing ■ Enables joining of dissimilar metals (e.g., copper + aluminum, aluminum + stainless steel, etc.) ■ Joint conditions can be numerically managed, ensuring reproducibility and stable quality ■ Environmentally friendly ■ Cost reduction is possible *For more details, please refer to the PDF document or feel free to contact us.

Our company offers "valves with limit switches" as products that assist in the safety management of factory equipment. Since the open and closed states can be output as signals externally, it is possible to prevent operational mistakes and oversights such as forgetting to open or close. As a comprehensive valve manufacturer, we can propose safety measures aimed at preventing malfunctions on-site and adding interlocks. 【Product Lineup】 ◎ Bronze Ball Valve (screw connection) Material: Bronze, Nominal Diameter: 15A to 50A ◎ Stainless Steel Ball Valve (screw connection) Material: SCS14A, Nominal Diameter: 8A to 50A ◎ Butterfly Valve (wafer connection) Material: FCD450, Nominal Diameter: 50A to 300A ◎ Bronze Gate Valve (screw connection) Material: Bronze, Nominal Diameter: 15A to 50A *You can view materials containing case studies and details of the lineup from the download button below.

Pressure gauge needle A cock (Bronze 20K) ◇ Convenient 90° open/close design... The handle's open/close status is clearly visible at a glance. ◇ Easy adjustment of pressure gauge orientation... The lock nut structure allows for arbitrary adjustment of the pressure gauge's direction. ◇ No need to prepare gaskets for the pressure gauge... A sealing O-ring is standard equipment. ◇ Measures to prevent condensation are possible... The long-neck handle allows for insulation and cooling construction up to 30mm. ◇ Reduces fluctuations in the pressure gauge pointer... The needle valve seat reduces fluctuations in the pressure gauge pointer caused by pulsation.

Daiwa Valve Co., Ltd. started providing BIM data in 2026. BIM stands for Building Information Modeling, which is a method of creating 3D data of buildings that replicate design, structure, and equipment on a computer, encompassing everything from design to construction and project management. Please feel free to contact us when you need our services. [Overview] ■ The BIM data we provide is a family created with "Autodesk Revit 2021." ■ We can also provide data converted from "Autodesk Revit" for "Rebro." * "Rebro" is a CAD for building equipment developed by NYK Systems Co., Ltd. * For more details, please download the PDF or feel free to contact us.
