Features and Advantages

● High-performance butterfly valves are ideal for on/off and throttling control of gas and liquid media.

● These valves provide bidirectional zero-leakage sealing, high flow capacity, and long service life.

● Double-eccentric butterfly valves feature a dual-offset stem design.

● The shaft is offset from the centerline of the disc: this offset ensures a continuous sealing surface on the disc when the valve is fully closed.

● The shaft is offset from the pipeline centerline: this offset ensures that the disc does not contact the seat when the valve is fully open.

● This double-eccentric design creates a cam-like action as the disc swings in and out of the seat. The disc immediately lifts off the seat, eliminating wear points at the top and bottom of the seat. The reduction of friction extends seat life, lowers operating torque, and improves throttling performance.
