Since 1975, we has been rooted in Nantun District, Taichung City, focusing on the production and sales of hydraulic valve products. Over the years, we have continuously innovated, committed to developing a variety of valve solutions, and worked closely with local supply chains in Taiwan to ensure the high quality of our products.

Our cartridge valve product line, branded as Sunstar, has successfully expanded into the global market. Currently, our cartridge valve products are recognized and used by customers in over 20 countries. These products are known for their compact size, large capacity, and high reliability. The standardized valve body design simplifies hydraulic circuit processing and makes installation and removal more convenient, especially suitable for the automotive and machinery fields.

In recent years, we has continued to provide comprehensive solutions to our customers. We have developed a series of proportional cartridge valve controllers, offering more choices and flexibility to our customers. We believe that through constant innovation and improvement, SUNNY will continue to lead the future of hydraulic valve products.
