28 Years Later: The ‘Valve’ Remains Fully Open

Time is the best test. In 1997, Guangdong Yunliu Lianfa Company purchased a triple-eccentric metal hard-seal butterfly valve from Xuanda Industrial Group for the "250,000-ton pyrite-to-acid project". After 27 years of operation, it still maintains a stable working condition.

This valve has always been installed at the inlet of the fluidized bed furnace. This "extra-long standby time" is not only a testament to quality, but also inseparable from the meticulous maintenance and trust placed in us by Yunliu Lianfa. Xuanda Industrial Group is deeply proud of this; it is the choice and trust of our customers that gives life to our products and together we have created this remarkable story of quality.

It began with a transaction, stemmed from quality, and endured through trust. This collaboration with Yunliu Lianfa Company will inspire Xuanda Industry to continue upholding its original aspiration that "quality is the lifeline of the enterprise," ensuring that we never slacken in our valve research and development and production. Furthermore, years of close cooperation have made us deeply aware that good products must stand the test of time.

Twenty-eight years have passed, and while Xuanda's production lines have been upgraded and its technology iterated, its original aspiration of "making good valves" has never changed. Grateful for Yunliu Lianfa's more than two decades of partnership, we will continue to prioritize quality and live up to every trust placed in us.
