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.
The valve has excellent throttling characteristics with good low flow control capability, which offers an inherently higher rangeability. This feature of IVEX series makes them ideal for the flow control / modulating duties. An adjustable gland box type shaft sealing arrangement permits on line adjustment of the packing to ensure zero leakage.
The fire safe version, IVEX - F model has been fire tested and certified as per the requirements API 607 standard by Lloyd's Register of Shipping & API 607 Edn. V by Bureau Veritas and TUV.
