Combining enduring performance with flawless design.
A real workhorse from the IV stables, the IVGK and 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 that allows minimum flow restriction.
The absence of a seat substantially reduces the valve operating torque requirement and makes the valve very effective for flow control/regulation duties. IVR is an ideal choice for furnace airflow and combustion control applications.
The wafer-style body has a universal design to fit between pipe flanges of almost all popular flange standards and is also available in a wafer-lugged body.
