Calculate the Valve Size

With the above information, the following steps are used to correctly size a valve in a piping system.

  1. Cv value is obtained by using the appropriate ANSI/ISA–75.01.01 flow sizing formula or computer aided flow control sizing program that is based on these formulas.
  2. Cavitation is checked by using the FL value (Liquid Pressure Recovery Factor), and the expansion factor needed for compressible fluids is obtained using the values (Pressure Drop Ratio Factor). Both values are found in the Cv charts supplied on the following pages.
  3. Select a nominal valve size from the Cv charts based on the calculated Cv.
    V-Port Ball Valves: Select a valve which offers calculated Cv for the minimum and maximum flow between 20% to 80% of port opening.
    Round Port Ball Valves: Select a valve which offers calculated Cv for the minimum and maximum flow between 30% to 80% of port opening.
  4. Select the valve type (flanged, threaded or welded) and materials of construction.
  5. Valtorc recommends RTFE valve seats for V-Ball Control Valve applications.
  6. Select the actuator – for Actuator Sizing please see our actuator product pages and IOM doucments.
