DOUBLE OFFSET
FIRE SAFE
HIGH TEMPERATURE SERVICES
The axis of the disc rotation is double offset to the seat.
When the disc rotates it unseats at a small turning angle by its cam effect. This outstanding feature enables.
Bubble tight shut-off over extended period of service.
Greatly reduced seat wear.
Reduced torque peak experienced with conventional valves.

A Secondary lip type, pressure assisted, metal seat gives BI-DIRECTIONAL sealing once the PTFE seat burns away after the fire.

CERTIFIED BY LLOYDS REGISTER OF INDUSTRIAL SERVICES. AS PER API 607

4th EDITION.

Combination of seat and disc materials suitable up to 6000C (11120F) Seat Leakage Rate
