Wear Resistant Putty (WR-2)
The faces on this valve would receive extreme wear from processing raw sewage and other foreign materials. Past repair method was to either surface harden [hard face], or simply replace when required. Valve replacement cost was estimated to be $1K.
The valve was sandblasted to a SSPC-SP5 white metal finish. Complete repair area was chemically cleaned using Cleaner Blend 300. Wear Resistant Putty was mixed and applied filling all cavitated and corroded areas. Acetone was used to smooth and sculpt Wear Resistant Putty following gel point. Devcon's repair cost was $100.
