Downloads and Specification Sheets
Rangeability of a control valve may be defined as the ratio of its maximum controllable flow rate to its minimum controllable flow rate.
The Shutter Valve far exceeds the rangeability of other valve types, while maintaining a compact design and very low torque requirements.
