Shutter Valve Catalog
This catalog shows the features that make the Shutter Valve the first major innovation in flow control in the last 50 years. The parts schedule and application areas are also included.
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.
Liquid Flow Charts
The downloads below show the flow characteristics for various Shutter Valve sizes in the full open condition, at estimated volumetric flow rates (US GPM) & pressure drop at the various flow velocities (ft/s). Assumed media is 60 degree F water.
