Post on Nov 5. Yet another real workhorse from the IV stables, IVTL model Butterfly valve incorporates the optimum design features to provide long trouble free service in the field. The IVR model Butterfly dampers, offered by Intervalve India are essentially seatless Butterfly valves intended for low pressure gas lines and air lines.

Foanges thickness of the portion of the flange which connects it to the pipe should be not less than the pipe thickness nor more than 3 mm flwnges.

This general purpose soft seated Butterfly valve has a fully rubber lined single piece body with a centric disc construction and is available in wafer lugged style body pattern to ensure precise location in pipeline. The mechanical stopper provided on the valve body ensures precise valve closing every time to ensure specified seat tightness.

Where machining is carried out it may be either by spot facing at the bolt holes or by back facing at the option of the manufacturer. The ISI Mark on products 63392 by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under-a lfanges system of inspection, testing and qualit control which is devised and supervised by ISI and operated Ly the producer.

Use this table also for nominal sizes 6 to 65 mm for 1.

The lightweight construction with the narrow wafer body enables easy fitment of these valves in ducts, manifolds and exhaust lines without additional support or strengthening of pipe lines.

The valve has excellent throttling characteristics with good low flow control capability, which offers an inherently higher rangeability. The disc has a spherical profile and comes out of contact with seat in the initial opening itself. The double offset disc design nearly eliminates the seating wear due to the camming action of the disc during closing. The type of protector and method of attachment shall be approved by the purchaser.

The lugged version with threaded holes can be used as end of line valves or terminal end valves. The valve is available in ‘wafer’ as well as ‘wafer lugged’ version with a host of seat and encapsulation material to cater to majority of the chemical process industry requirement.
