IVGE 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.

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 PN 10. The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards.

  • Full PN 10 pressure rating for the entire range of DN 50  to DN 350.
  • 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 lubricating shaft bearings (PTFE coated stainless steel) for both drive end and non-drive end shaft ensures minimum bearing friction torque.
  • Square coupling disc drive arrangement 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.
  • Excellent adaptability for actuated operation through standardised top flange dimensions for actuator mounting.
  • Seat liner extending on to the flange contact faces of the body eliminates the need for separate flange gaskets.
  • Controlled compression of the gasket sealing face to offer optimum sealing and prevent gasket face crushing due to over tightening.
