Globe Valve Assemblies
The TAC VA, VF, and VS-7000 and -9000 series
Linked Globe Valve Assemblies are complete
actuator/valve assemblies that accept two position,
floating, or proportional control, respectively, from a
DDC system or from a thermostat, for control of hot
water, chilled water and steam coils. These valve
assemblies consist of linked spring return and
non-spring return actuators mounted on 1/2" up to 6"
(15 mm to 150 mm) 2-way and 3-way globe valve
bodies, using a specially designed linkage assembly.
3-way assemblies are available for mixing (1/2" to 6")
and diverting (1/2" to 2") applications. This linkage uses
a rack and pinion mechanism to translate the rotary
motion of the direct-linked actuator into the linear
motion necessary to lift or lower the valve stem.
Typical applications include reheat on VAV boxes, fan
coil units, hot and chilled water coils in air handling
units, unit ventilators, and central system applications.
Linkage kits are available separately to allow field
assembly of TAC DuraDrive actuators to valve bodies.
Actuator/Linkage Assemblies
The Actuator/Linkage Assemblies consist of MA, MF,
and MS actuators pre-assembled to linkages that are
designed to be fitted onto 1/2" to 2" (15 mm to 50 mm
metric) VB-7000 and 2-1/2" to 6" (65 mm to 80 mm
metric) sizes of VB-9000 globe valve bodies.
