In-Line Seat Replacement

During the repair process, it is not uncommon to discover a steam cut or cracked valve body seat. To avoid the costly and time consuming process of removing the valve body from line, SVI has designed equipment and developed procedures to machine out integral body seats, apply new hard face overlay weld met, then re-machine welded area to re-create the original seating surface. Once completed, NDE examinations are performed on the new seat surface to verify there are no defects. This process has been performed many times by SVI in gate, globe and check valves.
