Live Loading Packing Gland

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.

Metal- to- Metal Patented Sealing System

Stellite Alloy HRC 40- 60 degree centigrade

Disc Position indication

Stem end provides fool- proof verification of disc location.

Universal Mounting

Actuator Mounting Plate and Stem Connection conform to ISO5211

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.
