VX-731X-5XX Series
Three-Way Globe Valve Assembly
VA, VF, and VS-731X Series Linked Globe
Valve Assemblies
The TAC VA, VF, and VS-731X-5XX series Linked Three-Way
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 and chilled water coils. These valve
assemblies consist of spring return actuators linked to 1" to 2"
(25 mm to 50 mm) three-way globe valve bodies. Three-way
assemblies with MX41-707X and MX41-715X actuators are
available for mixing applications only. A rack and pinion
translates the rotary motion of the actuator into the linear
motion of the valve stem.
Application
Typical applications include hot and chilled water coils in air
handling units, and unit ventilators.
Linkage Kit (AV-602) is available separately for field mounting
of TAC DuraDrive actuators.
