Professional CV Calculator
Accurately calculate valve flow coefficients to select the most suitable valve for your fluid control system
CV Calculator for Valve Sizing
This calculator can be used to help select a valve with enough flow capacity for a given application. The valve flow coefficient (Cv) is a convenient way to represent flow capacity of a valve across a range of fluids and process parameters.
Gas pressure units are in absolute pressure, except for PSIG.
Safe Product Selection
When selecting a product, the total system design must be considered to ensure safe, trouble-free performance. Function, material compatibility, adequate ratings, proper installation, operation, and maintenance are the responsibilities of the system designer and user.
