The valve’s unique design totally eliminates media contact with any metallic surface of the valve. NOTE 2 – The minimum tensile strength been specified in the relevant specifications. All dimckonr N–Far in millimetres. The valve has excellent throttling characteristics with good low flow control capability, which offers an inherently higher rangeability. IVR is an ideal choice for furnace air flow and combustion control applications.

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. If repairs by welding arc carried out, the castings shou! The IVR model Butterfly dampers, offered by Intervalve India are essentially seatless Butterfly valves intended for low pressure gas lines and air lines. The valve is available with 3 distinctly different seat design versions, viz.

The term integralflange applies to flanges integralwith pipes, valves and2. Home Documents IS For details reference may be made to IS: The valve has a fully rubber lined body and a rubber encapsulated disc with a square slot for the drive end shaft.

The PTFE seat liner covers the entire wetted surface of the body and extends on to the flange contact faces, thus eliminating possibility of any media contact with the body metal.

Even though the body is designed for a maximum pressure of 2. Flanges not integral Machined at Back.


The lugged version with threaded holes can be used as end of line valves or terminal end valves. Carbon and Carbon Matzganese Steele 1.

All dimensions in millimctres. 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 disc flap is held in position by a stub shaft with an axial locking arrangement provided on the top shaft. Where there is no application standard the method of attachment shall be the subject of agreement between the purchaser and the manufacturer. If the difference is more than 3 mm, it may be ncgotiatcd in a slope of 1 in 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.

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 fully circular back up elastomer and live loaded disc shoulder sealing ensures bubble tight closing of the Valve with zero shaft leakage. 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.

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.

When the welding of defects is permitted, the welding rod shall be such as to produce a weld having characteristics similar to the parent metal. Use this flajges also for nominal sizes 6 to 65 mm for 1. Intervalve’s GKL series valves are designed to flangs the demanding requirements of the general utility valve market with the HVAC segment in particular. API category B Pressure temperature rating: The type of protector and method of attachment shall be approved by flangee purchaser.

He shall be at liberty to reject any material which does not comply with the requirements of this. After welding, flanges shall be heat-treated, except that welds required for finish- and appearances only need not be heat treated, if approved by the purchaser. The purchaser shall specify the weld preparatio? 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.
