Triad Easy Valve Sizing Tool

Triad offers a quick Cv calculator that allows users to determine the proper size of the valve by merely entering the desired flow and flow conditions for each valve application.

This tool helps determine the proper valve size selection based on the flow rates of the various valve types. Our valve flow rates can be found here:

Please Note: This tool does not determine or warn if there is a possibility of Cavitation and or Excessive Noise Levels. Further discussion with a factory representative should be considered if there is any concern that these conditions might exist.
