OpDX

The OpDX high performance butterfly control valve uses the pressure-assisted seat concept to achieve bi-directional bubble seal closure while maintaining low breaking torque requirements. The OpDX is suitable for ANSI grades 150 to 600 and 2 "to 36" with a featured disc for throttling.

Metal and soft seats available

Configurable with metal (ANSI Class IV) or soft seat (ANSI Class VI)

The eccentric disc is lifted from the seat to prevent wear

Precise throttling enables improved parabolic geometry machining to the seat

Robust and lightweight flangeless wafer body

The MSS SP-67 face to face flange bolts are shorter than ball valves or eccentric plug valves, increasing safety and reducing the possibility of leakage
