Q5022
The Q5022A,B Globe Valve Linkages
connect one or two Honeywell direct
coupled rotary actuators (DCA) to a
globe valve for control of chilled water,
hot water, or steam. The Q5022A,B
Linkages are compatible with 2 and
3-way globe valves up to 6 in. (DN150)
pipe size.
Q5022A is used to provide enhanced
close-off ratings with Honeywell globe
valves up to 3 in. with 1-3/8 in. diameter
bonnet and 3/4 in. stem stroke.
Q5022B is used with Honeywell globe
valves 4 to 6 in. with 1-7/8 in. diameter
bonnet and 1-1/2 in. stem stroke.
