Four Decades of Valve
Innovation and Expansion

In 1985, CTGV began as a small valve workshop in Yongjia, a region known as China’s “Pump & Valve Capital.” What started as a modest venture steadily transformed—driven by dedication to quality, innovation, and long-term vision.

By 2005, CTGV had grown into a nationwide sales powerhouse. Five years later, the company officially evolved into Tiangong Valve Group Co., Ltd., backed by a registered capital of RMB 115.8 million. This transformation marked not just a change in scale but a bold commitment to becoming a full-service industrial valve partner.

With manufacturing bases in both Wenzhou and Yongjia, and a growing portfolio of 8 subsidiaries covering R&D, casting, trade, and petrochemical applications, CTGV has built an integrated, forward-looking ecosystem. Each step in our history reflects a single belief: great engineering builds lasting trust.
