Val-Matic is the only manufacturer to have NSF/ANSI 61 certification for a rubber seated ball valve for use in drinking water systems. The Ener•G Ball Valve features the advantage of a two-piece design with a fusion bonded epoxy interior/exterior coating and a bidirectional resilient Tri-Loc Seating System. The Tri-Loc Seat Retention System provides a low friction, wear resistant seat and allows easy adjustment or replacement of the seat without removing the valve from the line.
