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.
