First, you need to be able to obtain the serial number from Fisher Company; it contains detailed information about the valve’s production, including the material used for the valve, its pressure rating, sealing class, connection type, as well as the materials and manufacturing processes used for the internal components, bolts, gaskets, packing, and so on. However, which specific parts are used can only be known by Fisher’s internal staff
