As a joint-stock enterprise (formerly known as Shandong Valve Factory), we have been dedicated to the manufacturing of valves and valve cores for over 45 years. With a registered capital of 16.8 million yuan, a total area of 60,000 square meters, and a building area of 37,000 square meters, our company has experienced continuous growth since the restructuring in 2007. We are fully equipped to produce high-quality products that meet international standards, covering human resources, economic management, technical equipment, production processes, and supporting facilities. Our "Gaotian" tire valves are widely used in inner tubes, tubeless tires, and various types of tire rims.
We currently offer more than 100 different types of valves, with an annual output exceeding 200 million sets, along with 8,000 tons of valve copper. Our commitment to quality is reflected through several key certifications, including ISO/TS16949:2009 by ISR in November 2011, ISO9001:2008 by Beijing Zhongrun Certification Co., Ltd. in September 2013, and CE certification by National Quality Assurance (NQA) in March 2014.
Guided by a quality policy centered on "quality orientation, honesty and credit, continuous improvement, and customer satisfaction," and a business philosophy of "tolerance, innovation, and integrity," we strive to build long-term partnerships with domestic and international clients, working together for mutual success.
