VA-720x Series Electric Valve Actuator
Code No. LIT-1924180
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.
