Electric Valve Actuator
I ntroduction
The VA-720x Series synchronous motor driven
actuator provides floating or proportional control of
valves, with up to 19mm stroke in heating,
ventilation and air conditioning applications.
This compact, non-spring return actuator has a
1000N nominal force and responds to a variety of
input signals.
The VA-7200 Series can be easily field mounted
or ordered factory coupled to VG7000, VG8000,
VG9000 and VGS8000 Series valves in
accordance with the specified maximum close-off
pressure ratings (see pertinent valve bulletins).
VA-7200
Features and Benefits
