IVEX-M Series

 For an unbeatable, robust design, the IVEX-M stands as the top choice.

The ultimate in high-performance Butterfly valves, IV’s IVEX – series incorporates the ‘state of the art’ valve technology to outperform 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 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 the seat in the initial opening itself.

For those requiring absolute robustness, the IVEX-M variant stands out. Its metal-to-metal seating ensures maximum durability and resistance at elevated temperatures. The flexible metal seat offers high sealing capability with controlled leakage rates. The design of the clamping ring ensures that the metal seat has positive sealing against the disc contact surface, enabling consistent performance over its lifecycle.

The wafer-style body has a universal design to fit between pipe flanges of almost all popular flange standards. It is also available in a wafer-lugged body and double-flange body. Available in Class 150 and Class 300 Pressure Class.
