SVI Industrial’s manual valve repair capabilities are unparalleled. Each of our skilled technicians is highly experienced with gate, globe, check valves, metal or resilient seated ball valves, butterfly valves and sleeved and lubricated plug valves.

These services can be performed in our main facility in Pineville NC, our four satellite facilities in Cartersville, GA, Wilmington NC, Narrows VA, and Mt. Vernon IN, or any of our seven mobile units at our customer’s locations.

Along with our stationary manual valve repair, machining and welding equipment, we also have a large fleet of portable equipment in our extensive inventory including portable manual valve testing equipment and a test stand to perform shell and seat tests in accordance with API 598 and API 621. We also have extensive experience performing in-line manual valve seat replacements. As an alternative, our portable machining and welding equipment enable us to cut out manual valves, perform proper repairs or modifications and weld them back in place. We are capable of replacing stellite seats, and our technicians are factory trained in actuator repair for virtually all valve brands. These repairs and modifications can take place in our shop or at our customers’ locations, making us a turnkey provider for all of your manual valve repair and maintenance needs. These resources, along with our very dedicated and talented crafts personnel, have not only enabled us to perform seat replacements, but to also weld, repair and machine backseat packing gland area, bonnets, pressure seal gasket cavity and manufacture new stems to OEM specifications.
