    Valve Selection Guide D 35

    Uploaded by

    arrikan
    This document provides a valve selection guide to help engineers select the appropriate type of valve for different applications based on the conveyed fluid, nature of the fluid, valve function, and type of disc. The guide includes a table that lists common valve types suitable for liquids, gases, and solids that are neutral, corrosive, hygienic, slurries, fibrous suspensions, and abrasive powders. The table can be used to select the right valve for applications requiring on/off or control/modulating valves.
