APPLICATION & CONFIGURATION
Additional Information
Opening and flow information
The opening-angle/flow-coefficient illustration is qualitative only. Its percentage scale is not sufficiently defined to reproduce reliable numerical sizing coefficients. Obtain approved flow data before sizing.
Illustrated configurations
Configuration A depicts DN40-DN300 and Configuration B depicts DN350-DN600. The illustrations do not establish the configuration of larger tabulated sizes.
