VALVE ACCURACY SPECIFICATION


>
Woodward valves are designed to provide excellent accuracy at start flow and at max flow

> Methods for defining accuracy do not adequately address both ends of the valve performance

> Percent of full scale accuracy is used at the high end

> Percent of point is used at the low end

> Combining the two accuracy definitions results in more repeatable and accurate performance across the entire operating range
