The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards. When the welding of defects is permitted, the welding rod shall be such as to produce a weld having falnges similar to the parent metal. The lugged version with threaded holes can be used as end of line valves or terminal end valves.

If repairs by welding arc carried out, the castings shou! The ultimate fkanges high performance Butterfly valves, IV’s IVEX-series incorporates the ‘state of the art’ valve technology to out perform the competition. Developed By Trillion IT. An adjustable gland box type shaft sealing arrangement permits on line adjustment of the packing to ensure zero leakage.

The IVR model Butterfly dampers, offered by Intervalve India are essentially seatless Butterfly valves intended for low pressure gas lines and air lines.

The integrally moulded spherical profile seat with a matching profile on the disc shoulder both closed die moulded ensures fkanges sealing with minimum operating torque and prevents any fluid ingress into the shaft 66392. These shall Abe screwed in 6 shall as agreed be prepared theto between7. Intervalve’s GKL series valves are designed to meet the demanding requirements of the general utility valve market with the HVAC segment in particular.


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 purchaser flangds specify the weld preparatio?

All dimensions in millimetres. Alloy steel flanges shall be marked with the symbols designated in Table 1. IVR is an ideal choice for furnace air flow and combustion control applications. 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.

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 fllanges style body pattern to ensure precise location in pipeline.

Different Drilling Standards For 150# Flanges

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.

Values other steels will be included when available. The fully circular back up flanfes and live loaded disc shoulder sealing ensures bubble tight closing of the Valve with zero shaft leakage.

Flanges not integral Machined at Back. The valve has a fully rubber lined body and a rubber encapsulated disc with a square slot for the drive end shaft. For alloy steel studs or bolts, nuts of a similar steel, If carbon steel is used, it shall have but of a different qrade shall be used.

The valve is available with 3 distinctly different seat design versions, viz.

If the difference is more than 3 mm, it may be ncgotiatcd in a slope of 1 in 5. 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.

After welding, flanges shall be heat-treated, except that welds flnges for finish- and appearances only need not be heat treated, if approved by the purchaser.

Norm — The two types of Ranges shown arc alternatives at the option C 70 80 80 80No. API category A Valve face to face dimensions: 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. The valve’s unique design totally eliminates media contact with any metallic surface of the valve.

The disc flap is held in position by a stub shaft with an axial locking arrangement provided on the top shaft. Use this table also for nominal sizes 6 to 65 mm for 1.
