The Goggle valve is used for the isolation of Blast furnace gas/toxic or inflammable gases in the
furnace, and converter gas pipelines.
TECHNICAL DESCRIPTION:
The valve mainly consists of the body, disc, compensator bellow, clamping/de-clamping mechanism, disc
centering mechanism, and drive mechanism. These valves can be operated in auto as well as manual

clamping of seats, and vent valve operation (opening or closing). The valve is designed for jam-proof
operation under extreme operating conditions.
