South Valve has established a consistent and very strict quality inspection team from raw material production to final product assembly. Our company has its own physical and chemical laboratory, the use of professional instruments for testing, from the source material composition, hardness and other aspects of the test, to ensure that each valve is a high-quality product. Through the introduction of new technology, the entire production process can be visualized, and customers can track the production progress of products online through the visualization software independently developed by our company.
