菅沢製機 List of Products and Services

The technology that the Sugazawa Group aims for is "artisan skills." The cutting-edge machines, combined with the expertise of skilled staff, are used in excellent products such as machinery, hydraulic equipment, diesel engine fuel injection for ships and generators, and aircraft parts. Here, we introduce a product example of hydraulic components (switching valves). This product is an electromagnetic pilot switching valve used when there is a need to mitigate shock during switching, whether for high flow rates or relatively low flow rates. [Example] - Body material: FCD450, 500 - Spool material: SCM415 (case-hardened with a hardness of HRa82 to 84) *For more details, please refer to the PDF document or feel free to contact us.
