IVGE Butterfly valve
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
Key Features:
- 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.
