Product Bulletin
PB_VA-704x and VA-706x
Issue Date 05 2009
The VA-704x and VA-706x actuators provide ON/OFF
or proportional control in HVAC applications.
The compact design of these actuators make them
suitable for installations in confined spaces, such as
fan-coil applications.
The VA-704x and VA-706x actuators are designed
for field mounting onto VG5000, VG4000 and V5000
terminal unit valves (see pertinent bulletins).

Actuator combinations
The VA-704x and VA-706x series thermal valve actuators are designed to be used with the V5000, VG5000
and VG4000 valve series.
Please refer to the “VG5000 Forged Brass Valves”, “VG4000 High Capacity - High close-off Terminal Unit
Valves” and “V5000 Terminal Unit Valve” Product Bulletins for complete ordering information.
Operation
VA-704x Actuators
The actuators allows the choice for:
Direct Acting
Extend VA-7040-2x
VA-7047-2x
or
Reverse Acting
Retracts VA-7048-2x
Normally Closed configuration (Direct Acting)
When energised, the actuator pushes down axially
on the valve stem against the force of the valve
return-spring to open the normally closed port of the
valve.
When the actuator is de-energised, the valve return-
spring brings the valve back to its normal position
against the pressure of the fluid.
Normally Open configuration (Reverse Acting)
When the actuator is energised, the valve return-
spring brings the valve to the closed position against
the pressure of the fluid.
When the actuator is de-energised, the actuator
pushes down axially on the valve stem against the
force of the valve return-spring to open the normally
closed port of the valve.
VA-706x Actuators
The valve aperture is proportionally to the control
signal (DC 0 to 10 V) of the controller.
The action of the actuator can be set by energizing
the white or red wire.
