The ultimate in high performance Butterfly valves, IV’s IVEX-series incorporates the ‘state of the art’ valve technology to out perform the competition. The double offset disc design nearly eliminates the seating wear due to the camming action of the disc during closing. The mechanical stopper provided on the valve body ensures precise valve closing every time to ensure specified seat tightness. The disc has a spherical profile and comes out of contact with seat in the initial opening itself.

The valve is available with 3 distinctly different seat design versions, viz. Soft seated, Fire safe and Metal to Metal seated with wafer or wafer lugged body option
