Intervalve Butterfly Valve model IVGE / IVTLE is an economical answer to the corrosion problems faced by Chemical process industries with conventional metal seated Butterfly valves. The valve’s unique design totally eliminates media contact with any metallic surface of the valve. The valve has a fully rubber lined body and a rubber encapsulated disc with a square slot for the drive end shaft.

The integrally moulded spherical profile seat with a matching profile on the disc shoulder (both closed die moulded) ensures perfect sealing with minimum operating torque and prevents any fluid ingress into the shaft bores.

The valve is available in ‘wafer’ as well as ‘wafer lugged’ version with a host of seat and encapsulation material to cater to majority of the chemical process industry requirement.
