c - Maximum allowable differential across the valve in any open position. Recommend less than 20 psi for quieter service. Consult
close-off pressures.
d-
Dual actuators are not available as factory assemblies.
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.
3-Way Globe Valve Assemblies
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.
