The actuator delivers a minimum stem force of 180 lb.
Integral auxiliary switches are available for indicating
end-stop position or to perform switching functions. For
proportional models a 0 (2) to 10 VDC signal feedback
is available.
VA7820/VA7830 Series Electric Actuators
The VA7820/VA7830 Series is a line of motor driven,
direct mount, spring return actuators that operate on
24 VAC. The actuators ship already set for 0 to 10 VDC
Proportional control. With a simple change of DIP
switch settings, the actuator can be reconfigured in the
field for On/Off (Floating) Control. Position feedback is
available via switches or a 0 (2) to 10 VDC signal. The
actuator delivers a minimum stem force of 180 lb. If the
power fails, the automatic spring returns the valve stem
up for the VA7820 actuator or the valve stem down for
the VA7830 actuator. A manual override allows manual
positioning of the valve when power is not available.
The actuator is available factory mounted to 1/2
through 2 in. valves body styles with NPT (threaded)
end connections. The actuator is available separately
for field mounting to union sweat, union globe, and
union angle VG7000 Series valves.
