CAVITATION CHART
After selecting the valve size, locate inlet and outlet pressures on this chart. If the intersection point falls
in the shaded area, cavitation can occur. Operation of valves continually in the cavitation zone should be
avoided. Consult Watts ACV for alternatives.
Cavitation Chart
NOTE: The above chart is a suggested guide. Inlet pressure, outlet pressure, minumum, normal and maximum fl ow rates should
be considered for specifi c valve sizing. Contact Watts ACV for details.
