Yet another real workhorse from the IV stables, IVTL 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 disc construction and is available in wafer lugged style body pattern to ensure precise location in pipeline.
The body liner which also functions as the soft seat, come either in a replaceable version or an integrally moulded (bonded) version and offers 100 % bi-directional sealing against vaccum to rated pressures of PN 10 or PN 16.
The lugged version with threaded holes can be used as end of line valves or terminal end valves.
