Problem:<br />
This primary intake water butterfly valve would receive extreme abrasive <strong>and</strong> corrosive wear. The<br />
wear was so severe that the valve would leak. Previous method of repair was to simply replace when<br />
required. The valve replacement cost was estimated to be $40K.<br />
Solution:<br />
The complete valve assembly was s<strong>and</strong>blasted to a SSPC-SP5 white metal finish. All repair surfaces<br />
were then chemically cleaned using Cleaner Blend 300. Ceramic <strong>Repair</strong> Putty was applied to rebuild<br />
missing metal on the valve body <strong>and</strong> gate deeper than 1/8”. Following a partial cure of Ceramic repair<br />
Putty, (4 hours), Brushable Ceramic was applied to a thickness of 30 mils in two coats 15 mil each<br />
coat.. Brushable Ceramic provides a long lasting, corrosion <strong>and</strong> abrasion resistant, low co-efficient to<br />
friction protective surface coating. <strong>Devcon</strong>’s repair cost was $1.5K.
