Note: Choose a valve assembly having a close-off pressure capability sufficient for the application. Not all valve body and actuator combina-
tions are available factory-assembled. Some combinations must be field-assembled.

a - Models without actuator codes are not offered as factory assemblies. Purchase the actuator and the valve body separately and field assemble. For available
factory assemblies, consult the price schedule.
b - To determine a specific part number, see Pg. 46, Assembly Ordering Linked VB-7000 SmartX Globe Valves for the relevant part series.

d - Close-off ANSI IV (.01%) for soft seats.
e - Close-off pressure ratings describe only the differential pressure which the actuator can close-off with adequate seating force. Consult valve body specifications
for other limitations. The rating value is the pressure difference between the inlet and outlet ports.
f - Normally open (N.O.) assembly using stem up open valve body.
g - Normally closed (N.C.) assembly using stem up closed valve body.
j - Valve body and actuator size determine the close-off capabilities. Example: All ½”, 2-Way globe valves will make the same close-off regardless of the Cv rating
for a given actuator.
