Globe Valve Linkage

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.
