Double Offset Disc Design
The shaft is offset from both the valve centerline and seat centerline, reducing disc-to-seat contact during opening and closing for smoother operation.
Reduced Seat Wear
The double offset geometry minimizes friction between the disc and seat, significantly extending seat life compared with concentric butterfly valves.
Lower Operating Torque
Reduced sealing friction requires less operating torque, making the valve suitable for manual, pneumatic, and electric actuation while lowering actuator size and cost.
Bubble-Tight Shutoff
Soft-seated designs provide reliable bidirectional bubble-tight sealing, ensuring dependable isolation in demanding process applications.
