60 lb-in DuraDrive Proportional Actuator (24V)

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.
