Standard low emission stem seal with 0-20 PPM live-loading provides predictable and constant packing compression for more than 5000cycles before adjustment or re-packing.

Stellite Alloy HRC 40-60 degree centigrade

Disc Position indication

Stem end provides fool-proof verification of disc location.

Principle Of Operation

The SDF Triple Offset Butterfly Valve provides a bi-directional bubble tight shut-off. This geometry ensures that the disc seal contacts the body seat only at the final shut-off position without rubbing or galling, providing a torque generated resilient seal with sufficient“wedging”to ensure a uniform seal contact.

The triple offset geometry

OFFSET 1 The shaft is offset behind the seat axis to allow complete sealing contact around the entire seat.

OFFSET 2 The shaft centerline is offset from the pipe and valve  which provides interference free opening and closing of the valve.

OFFSET 3 The seat cone axis is offset from the shaft centerline to eliminate friction during closing and opening and to achieve uniform compressive sealing around the entire seat.
