Calibration Of The Products Weight

Every once in a while, we weigh all our products to calibrate the unit weight. This is mainly because the unit weight varies slightly due to different raw material batches, process adjustment, temperature and other factors. As providing accurate product specification to customers is one of our responsibilities, we weigh thousands of products regularly. Among all of our products, 'valve' is the heaviest section of our piping system. Here are some photos of big size valves. Let's take a glance at these valve giants. Obviously, CPVC DN200 swing check valve (Top-hinged Type) is the champion of this weight contest.
