Ceramic lined body
Valve Body has a 1/2" pre-engineered ceramic lining welded in place.

Power & Industrial Services designs a replacement for your Forney Burner Shut-
Off Dampers. Built to give you years of additional wear life, it has increased body strength, a ceramic lining, a ceramic coated seat ring, spare part interchangeability, and meets or exceeds NFPA 85 F standards for component design for pulverized fuel systems.

Our spare parts are interchangeable with Forney's.
