Valve Selection Guide

Applications guide for selecting valves based on conveyed fluid type, nature of fluid, valve function, and disc type. The suitability of a valve for a particular application is decided by the materials used in relation to the conveyed fluid as well as its mechanical design.

How to Use This Valve Selection Guide

Step 1: Identify the type of conveyed fluid (Liquid, Gas, or Solids)

Step 2: Determine the nature of the fluid (Neutral, Corrosive, Hygienic, Slurry, Fibrous Suspensions, etc.)

Step 3: Define the required valve function (On/Off, Throttling, or Control valve, modulating)

Step 4: Review the recommended valve types in the selection table

Important Considerations

  • Material Compatibility: Ensure the valve materials are compatible with the conveyed fluid to prevent corrosion and degradation
  • Mechanical Design: Consider pressure ratings, temperature limits, and flow characteristics
  • Application Requirements: Match the valve function to your specific application needs
  • Installation Environment: Account for operating conditions, maintenance accessibility, and safety requirements

For more detailed technical specifications, consult with valve manufacturers and industry standards.
