Discs
Renewable, regrindable bronze; precisely guided above and below me seating faces to prevent cocking.

Seats
Regrindable, integral seats are machined to precisely fit taper of discs.

Bodies
Proportioned for maximum strength, full flow. Large clearances at ends of pipe threads permit tight joints without pipe ends jamming diaphragms, distorting seat, or choking flow. Made of the highest quality steam bronze to resist wear and corrosion.

Balls
Stainless steel Provide multiple seating contacts. Wear is evenly distributed over entire area.

Bodies
Large flow area in body minimizes friction resistance. Metal distribution and thickness provide ample safely at maximum rated operating pressures. Large clearances at end of pipe threads permit tight pipe connections without danger of pipe ends jamming against diaphragms, distorting the seat or choking the flow.
