Turbine Valves

SVI has successfully performed the most critical turbine valve seat repairs. Utilizing our machine shop capabilities, we have fabricated custom seat grinding and lapping equipment capable of reaching the depths and diameters of large re-heat stop valves and control valves associated with turbine operations. In addition to lapping and grinding operations, we have successfully replaced the hard face overlays on seating surfaces both in our shop and in-line.

SVI has also developed a custom lapping machine and plate for seat lapping of turbine control and stop valves. The pictures bellow illustrate the before, during and after pictures of our custom lapping machine.

Our highly trained technicians, machinists and engineers can develop valve specific lapping equipment on an expedited basis to meet virtually any customer requirement.
