Description
The VA7800 Series of electric valve actuators
control VG7000 Series Bronze Globe Valves
in HVAC systems. The VA7800 Series
produce a minimum linear output force of
180 lb (800 N) and are ordered field mounted
or factory coupled to 1/2 through 2 in.
VG7000 Series Bronze Globe Valves. All
actuators are direct mount and available in
both spring-return and non-spring-return
models.
Spring-return models ship from the factory set
for DC 0 to 10 V Proportional Control. With a
change of DIP switch settings, this model can
be field configured to On/Off or Floating
Control. In addition to these settings, optional
auxiliary switches are also available.
Non-spring-return models are available in
AC 24 V On/Off (Floating) Control, or
DC 0 to 10 V Proportional Control. Models are
available with or without optional auxiliary
switches.
Refer to the VA7800 Series Electric Valve
Actuators Product Bulletin (LIT-12011474) for
important product application information.
Features
Automatic Stroke Adjustment — provides
easy, quick, and precise commissioning.
Manual Override as Standard — allows
manual positioning of valve for easy
commissioning and servicing.
IP54 Enclosure Protection — allows
installation in a wide range of
environments.
Unique Swing-Gate Yoke — offers fast and
secure attachment to the valve.
Brushless Motor — ensures low energy
consumption and long life.
Proportional Model — enables one model
to be used for various control types.
Force-Controlled Motor Shutoff — reduces
energy consumption, wear of the actuator,
and protects the valve from excessive
forces.
Stroke Position Indicator — gives visual
indication of valve operation, provides
automatic adjustment of stroke indicators
during first cycle of operation.
Status Light-Emitting Diode (LED) — gives
visual indication of actuator status and
assists with diagnostic.
Optional Integrated Auxiliary Switches —
provides adjustable switch points with line
voltage capability.
Integral Cable with Colored Conductors —
simplifies installation and field wiring.
VA7810 Electric Valve Actuator
Integral Connector for 3/8 in. (10mm)
Flexible Metal Conduit (FMC) — simplifies
installation and field wiring.
Underwriters Laboratories Inc.® (UL) and
CE Compliant — provides internationally
recognized regulatory agency approval.
Repair Information
If the VA7800 Series Electric Actuator fails to
operate within specifications, replace the unit.
