c - Maximum allowable differential across the valve in any open position. Recommend less than 20 psi
for quieter service. Consult close-off pressure ratings.
d - Dual actuators are not available as a factory assembly.
e - Mixing configuration, ports A and B are inlets, AB port is outlet.
f - Diverting configuration, flow AB to A port.
g - Diverting configuration, flow AB to B port.
h - All flow configurations, mixing or Diverting.

Note: Choose a valve assembly with a maximum operating differential pressure capability sufficient for the application. Consult close-off pres-
sure ratings. Not all actuator and valve body combinations are offered as factory assemblies.
