Magami A real workhorse from the IV stables, IVGK model Butterfly valve incorporates the optimum design features to provide long trouble free service in the field. Values other steels will be included when available.

Soft seated, Fire safe and Metal to Metal seated with wafer or wafer lugged body option. This general purpose soft seated Butterfly valve has a fully rubber lined single piece body with centric disc construction iss is available in wafer type body pattern. The valve has excellent throttling characteristics with good low flow control capability, which offers an inherently higher rangeability.

The top shaft sealing is through stuffing box type gland sealing arrangement, which is field adjustable. The lugged flangss with threaded holes can be used as end of line valves or terminal end valves. An adjustable gland box type shaft sealing arrangement permits on line adjustment of the packing to ensure zero leakage. Developed By Trillion IT. All dimckonr N—Far in millimetres.

Os — The two types of Ranges shown arc alternatives at the option The ISI Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under-a well-defined system of inspection, testing and qualit control which is devised and supervised by ISI and operated Ly the producer.

The disc has a spherical profile and comes out of contact with seat in the initial opening itself. The valve has a fully rubber lined body and a rubber encapsulated disc with a square slot for the drive end shaft.

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. However, a quality factor of 0. The IVR model Butterfly dampers, offered by Intervalve India are essentially seatless Butterfly valves intended for low pressure gas lines and air lines.

They shall be cleaned out to sound metal before welding, and shall be submitted to the purchasers inspector for approval in this condition, after which they may be welded if the purchaser so agrees.

The lightweight construction with the narrow wafer body enables easy fitment of these fkanges in iz, manifolds and exhaust lines without additional support or strengthening of pipe lines. Nominal SizeA continuous produced by a 3 mm radius round-nosed tool approximately 1. The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards. The fully circular back up elastomer and live loaded disc shoulder sealing ensures bubble tight closing of the Valve with zero shaft leakage.

For details reference may be made to IS: He shall be at liberty to reject any material which does not comply with the requirements of this. Post on Nov 5.

All dimensions in millimetres. NOTE 2 — The minimum tensile strength been specified in the relevant specifications. 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. If the difference is more than 3 mm, it may be ncgotiatcd in a slope of 1 in 5.

Ail dimensions in millimetres. The valve is available with 3 distinctly different seat design versions, viz. Carbon and Carbon Matzganese Steele 1. Use this table also for nominal sizes 6 to 65 mm for 1. The 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 thicker. These shall Abe screwed in 6 shall flanged agreed be prepared theto between7.
