A triple offset butterfly valve is often used in critical applications and is designed similar to a double offset butterfly valve. The third offset is the disc-seat contact axis. The seat surface takes a conical shape which coupled with the same shape at the ridge of the disc, results in minimal contact before full closure of the valve. A triple offset butterfly valve is more efficient and allows for less wear. Triple offset valves are often made of metal seats to create a bubble-tight shut-off. The metal seats allow butterfly valves to be used in higher temperature ranges.
High performance butterfly control valves are intended for general service applications not requiring precision throttling control.
They are frequently used in applications requiring large sizes and high temperatures due to their lower cost relative to other styles of control valves. Care is required in sizing and applying this style of valve to eliminate control problems associated with process load changes. They work quite well for constant process load applications. Designs using characterized contour are able to expand the control range to that of a segmented ball valve.
Available end connection styles include wafer, lugged, and double flange.
