VA-720x Series Electric Valve Actuator

Code No. LIT-1924180
Issued January 2, 2014

Description

The VA-720x Series Electric Actuator provides
incremental or proportional control of valves
with up to a 3/4 in. (19.05 mm) stroke in HVAC
applications.

The VA-720x is a non-spring-return,
synchronous, motor-driven electric actuator
featuring a 180 lb (800 N) minimum seating
force in a compact, easy-to-install package. It
accepts incremental control from a three-wire
24 VAC control signal or a proportional DC
control signal (up to 10 V maximum). The
VA-7203 also contains a 2,000 ohm position
feedback potentiometer.

The VA-720x Series can be easily field
mounted to VBC Series Bronze Cage Trim
Valves and factory or field mounted to
VG7000 Series Bronze Control Valves.

Features

• compact unit provides 180 lb force (800 N)
output covering a wide range of
applications with just one actuator

• magnetic clutch provides constant output
force for positive closeoff of valves and
protects motor in stall conditions

• durable construction provides longer cycle
life

• unique yoke design enables easy field
mounting to valves, reducing installation
and stroke adjustment time

• selectable direct and reverse action
simplifies setup and installation

• built-in resistor for current control provides
greater application flexibility

Applications

The VA-720x Series Actuator is used in
conjunction with VG7000, VT, Flare, and
Bronze Cage Trim Valves for hot-water and
chilled-water systems. For VG7000 Series
Valve factory mounted options, refer to the

VG7000 Series Brass Trim Globe Valves with
