MFSizing is a customized valve- and actuator-sizing program designed to be used with the Master Flo product line. It is suitable for Microsoft Windows 95 or higher operating systems. The software package includes an installation wizard.

The algorithm on which MFSizing is based has been developed according to the ISA S75.01 specifications for control-valve sizing. Calculations include the following:
1. Master Flo valve sizing and coefficient of valve capacity (Cv).
2. Pressure drops across the specified valve size at various flow conditions.
3. Flow rates based on valve size, Cv, and pressures.
4. Sizing for Master Flo pneumatic piston, hydraulic piston, and rotary stepping actuators.

The program can be run for multiple flow conditions simultaneously. All control parameters may be input in a broad variety of units. The output from all calculations is summarized in a printable report, and a save-to-file option is also available for electronic handling of the sizing results.

A comprehensive help menu allows for quick and easy reference to various program options. Also included is a glossary of terms commonly used in the valve industry.

MFSizing is continuously improved and updated. More features are added based on user requests and product development.
