Description

The VA7800 Series of Electric Valve

Actuators control VG7000 Series Bronze

Globe Valves in Heating, Ventilating, and Air

Conditioning (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 shut-off—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 a VA78x0-xxx-2 Series Electric Valve

Actuator fails to operate within specifications,

replace the unit. For a replacement actuator,

contact the nearest Johnson Controls®

representative.
