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. This general purpose soft seated Butterfly valve has a fully rubber lined single piece body with centric disc construction and is available in wafer type body pattern.

The body liner which also functions as the soft seat, comes in either a replaceable version or an integrally molded (bonded) version and offers 100 % bi-directional sealing against vacuum to rated pressure of PN10 or PN 16.

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

  • Unique triple sealing system for shaft sealing, eliminates any fugitive emission or secondary leakage.
  • Self  lubricated PTFE lined bearings for both drive end and non-drive end shaft ensures minimum bearing friction torque.
  • Seat liner extending on to the flange contact faces, eliminates the need for separate flange gaskets during installation.
  • Controlled compression of the gasket face to offer optimum sealing & prevent gasket face crushing failure.
  • Bi-directional valve with tight shut off sealing capability to hold vacuum to rated pressure in either direction.
  • Excellent adaptability for actuated operation through standardised top flange mounting dimensions for actuator fitment.
  • Suitability for ON /OFF as well as throttling duties.
  • Choice of seat and disc materials to suit media conditions and service requirements.
  • Adaptability to fit between companion flanges of all popular flange standards for the wafer style body.
  • Possibility of lower seat rating to obtain reduced operating torque and extended seat life for low operating pressures.
