DeZURIK Sizing & Selection Programs
DeZURIK provides the following sizing and selection programs to help you select the proper valve style and materials for your application. DeZURIK’s network of experienced and factory-trained independent sales representatives are able to offer assistance with applications, specifications, valve sizing, price quotations, and more. Please contact us if we can assist you in any way.
ALPHA I CONTROL VALVE SIZING PROGRAM
Alpha-I is a valve sizing tool that performs sizing calculations for DeZURIK control valves based on your process conditions. The calculated data will provide the information required by the user in selecting a suitable valve for the process conditions input. After the sizing calculations are completed, Alpha-I is able to predict the system characteristic and calculate the valve’s installed characteristic. The installed characteristic graph visually displays the relationship between flow rate and percentage open of the valve based on your process conditions.
To download, click the Alpha I icon logo above.
NOTE: The Alpha I (Version 21.5.12.0) program is an executable file (e.g. an .exe or .msi file). Some browsers will allow you to ok the download, but others may block access because hackers have been known to use this file type to infect computers. If you are unable to download Alpha I, please check with your IT department. If needed, we can send you a link to a shared file containing the program. Send requests to info@dezurik.com.
The following manuals and guides will assist you in using the Alpha I program to its full potential:
The Alpha I Instruction Manual describes the features of the program; system requirements; main screen overview; project, tag and size valve tabs; quick access toolbar options; static fields; process fields; calculated fields; filters and multiple valve sizing; printing; creating, saving and opening projects; tags; saving; sharing; backups; and deleting projects.
The Alpha I Reference Manual includes definitions to installed characteristics and the four system models used by Alpha I; inherent flow characteristic curves for DeZURIK control valves; velocity recommendations; properties of saturated steam & water, superheated steam, superheated steam and compressed water; compressibility factors; and sizing equations for liquids, gas and steam.
Alpha-I incorporates equations and methodology found in ISA RP75.23, Considerations for evaluating Control Valve Cavitation. The Alpha-I program, and this Cavitation Guide, will assist the user in making sound engineering decisions when faced with a cavitating control valve.
