Two-Way and Three-Way Globe Valve

Spring Return DuraDrive Actuators
Submittal Sheet
VA, VF, and VS Series Direct Mounted Globe
Valve Assemblies
The Invensys VA, VF, and VS-XXXX-5XX series direct
mounted, two-way and 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, chilled
water, and steam applications. These valve assemblies
consist of spring return linear actuators direct mounted to 1-1/
4" through 4" (32 mm through 100 mm) two-way and three-way
globe valve bodies. An integrated 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.

Close-off pressure ratings describe only the differential pressure which the actuator can close-off with adequate seating force. Consult valve body specifications
for other limitations. The rating value is the pressure difference between the inlet and outlet ports.
