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.

IVGE BUTTERFLY VALVE WITH PRESSED HANDLEVER
Full PN 10 pressure rating for the entire range of DN 50 to
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
