Xusheng Valves strict material selection, precision machining,each process layer strictly, semi-finished products in the process through the initial inspection before flowing into the next process, attention to detail and cast quality perfect Xusheng Valves.
For valves, pressure testing and temperature testing is required for each valve. After we get the finished products, we check for surface roughness, thickness equality, roundness, size measurement and sand holes again.
