VB6 SERIES 6-WAY CONTROL BALL VALVES AND ACTUATORS - INSTALLATION INSTRUCTIONS
31-00380M-02 Printed in USA 10
Flow Rate as per Valve Pressure Difference (ΔP)
*For fully open valve position.
For example:
The VB6A003+012+AL valve is with CV 0.30 (for sequence 1) and CV is 1.20 (for sequence 2).
If we consider the valve pressure difference (ΔP) 4 psid then as per above table, the Flow rate for
sequence 1 will be 0.60 gpm and for sequence 2 will be 2.40 gpm.
