Stainless Steel IVDF Butterfly Valve

The most sought after design by desalination plants and utility installations, IVDF represents the state of the art rubber lined Flanged double valve, meeting all the user industry requirements.

The double flanged body pattern ensures precise installation in pipeline, and can be used as an end to the line valve if required. The unique feature of this valve, is its adaptability for lined pipes, due to negligible disc protrusion beyond the body laying length. The universal square top shaft on valves upto DN200, enables easy change over from hand lever operation to actuated operation when required.

Key Features:

• Fully rubber lined body, with lining extending upto the flange contact face to make gasket free sealing.
• Ideal valve for installation with lined pipes, since the disc chord interference with pipe ID is negligible.
• Controlled compression of the gasket face offers optimum sealing and prevents gasket face crushing.
• Unique triple sealing system, for shaft sealing to ensure zero secondary leakage.
• Self lubricated PTFE lined bearings, for both drive end and non-drive end shafts, ensures minimum bearing friction.
• Bi-directional tight shut off sealing from vacuum to rated pressure.
• Excellent adaptability for actuated operation through standardized ISO top flange.
• Universal top square shaft enabling direct actuator fitment, after removal of Hand lever, for sizes upto DN200.
• Choice of seat and disc materials to suit media and operating conditions.
• Enables installation close to other pipe fittings, without disc interference.
• Preferred design for desalination plants, municipal water supply and Effluent plants.
• Adjustable bottom thrust pad / bearing for DN250 and higher to take care of axial thrust loading.
• DN600/DN650 size provided with “O Ring holder” type drive end shaft sealing arrangement for extra reliability.
