IVTLE model Butterfly valve incorporates the optimum design features to provide long trouble free service in the field. This general purpose soft seated Butterfly valve has a fully rubber lined single piece body with a centric, rubber encapsulated disc construction  and is available in wafer lugged body pattern to ensure precise location in pipe line.

The body liner which also functions as the soft seat, comes integrally moulded (bonded) version and offers 100% bi-directional sealing against rated pressures of PN10.

Key Features:

• Full PN10 pressure rating for entire range of DN50 to DB350.
• Bi-directional valve with sealing capability to hold rated shut off pressure in either direction.
• Unique triple sealing system for shaft sealing, eliminates any fugitive emission or secondary leakage.
• Self lubricated shaft bearings (PTFE coated stainless steel) for both drive end and non-drive end shaft ensures minimum bearing friction torque.
• Square coupling disk drive arrangements eliminates need for taper pins and exposure of metal parts to media.
• Spherically profiled seat and disc shoulder contact area ensures perfect sealing around the shaft bore and zero leakage.
• External locking arrangement for top shaft to make it blow out proof.
• Seat liner extending on to the flange faces of the body eliminates the need for separate flange gaskets.
• Controlled compression of the gasket face to offer optimum sealing & prevent gasket face crushing due to over tightening.
