Triple offset and ellipsoidal sealing geometry Butterfly Valves

Bi-directional bubble tight shut-off

Inherently firesafe by design

Developed Geometry results in:

-Zero seat/Seal friction

-Low torques

-Extended service life

-Continued seal through thermal cycling

-Torque seating

Excellent flow and throttling characteristics

covering services from cryogenic to high

temperatures.

Excellent control of fugitive emission by virtue of

rotary stem movement and advanced packing

materials.

　　 - Less than 50ppm on Fugitive

　　 Emission Test to cover EPA21
