Qiaofa Machinery Manufacturing Co., Ltd. Has developed and engineered a series of advanced, high-efficiency, energy-saving, and specialized steam trap valves. Utilizing new technologies, we have developed and produced a proprietary brand series of steam trap valves with independent intellectual property rights. Our product manufacturing processes involve analyzing and testing material properties through chemical testing, mechanical performance testing, metallographic inspection, and non-destructive testing. We rigorously analyze and observe the microstructure of metallic materials to strictly control and manage raw material performance.
