Heavy-duty, large diameter shaft to eliminate flexing and breakage; Dual shaft seals eliminate leakage.

PTFE bearing on shaft eliminates friction and wear; stem design is "blow-out" proof.

PTFE seats energized with O-rings eliminate wear and improve cycle life.

Trunnion design eliminates lateral ball stress and allow downstream piping to be disconnected under full line pressure.

Known as "The Engineered Ball Valve", Series MBV provides more safety and design features than any other thermoplastic ball.
