Product Overview

VG7000 Series Bronze Control Valves Product Bulletin 7
VA-8x2x Series Electric Actuators
The VA-8x2x Series Actuators are synchronous
motor-driven, force sensor limited, non-spring return
actuators that feature a 22 lb seating force in a
compact design. The VA-8020 accepts floating control
from a three-wire, 24 VAC control signal. The VA-8122
typically accepts proportional control from a 0 to
10 VDC control signal; however, it can be field adjusted
to accept signals up to 20 VDC. In addition, the
VA-8122 features an input signal reversing feature that
allows it to be used in both heating and cooling
applications.
Note: The VA-8x2x is only available factory mounted
on 1/2 and 3/4 in. valves. Because the VA-8x2x
requires a unique slotted valve stem for factory
assembly, it is necessary to select the S option in the
Stem Type section of Table 2.
M9116 Series Electric Actuators
The M9116 Series is a line of motor driven, non-spring
return actuators that operate on 24 VAC or VDC power
and are available for use with floating or proportional
controllers. When coupled with the M9000-500 Valve
Mounting, the rotary motion of this actuator is
converted into linear motion that will operate
1/2 through 2 in. VG7000 Series Valves. The actuator
and mounting deliver a minimum stem force of 180 lb in
both directions. A compression spring on the output
shaft of the mounting automatically compensates for
seat wear. Integral auxiliary switches are available for
indicating end stop position or to perform switching
functions. Position feedback is available via switches, a
potentiometer, or a 0 (2) to 10 VDC signal.
M9220 Series Electric Actuators
The M9220 Series is a line of motor driven, spring
return actuators that operate on 24 VAC or VDC power
and are available for use with on/off, floating, or
proportional controllers. When coupled with the
M9000-500 Valve Mounting, the rotary motion of this
actuator is converted into linear motion that operates
1/2 through 2 in. VG7000 Series Valves.
The actuator and mounting deliver a minimum stem
force of 180 lb in both directions. A compression spring
on the output shaft of the mounting automatically
compensates for seat wear. Integral auxiliary switches
are available for indicating end stop position or to
perform switching functions. Position feedback is
available via switches, a potentiometer, or a 0 (2) to
10 VDC signal.
M100 Series Electric Actuators
The M100 Series is a rotary actuator used to position
valves in HVAC and industrial applications. When
coupled with a VG7000-M1x0 Series Valve Mounting
Kit, the rotary motion of the M100 Series Actuator is
converted to linear movement. The mounting kit
includes an overtravel spring, which determines the
maximum seating pressure in conjunction with actuator
selection.
The M110, M120, M130, M140, and M150 Actuators
are only available for field mounting to VG7000 Series
Valves. See Table 5 for ordering information and
additional details. Kits are available to field mount all
M100 models; see Table 5, Table 8, and Table 10 for
detailed information.
The M120, M140, and M150 are non-spring return
actuators that will hold their position when
de-energized. The M110 and M130 are spring return
actuators that return the valve to its normal operating
position when the power is disconnected. A braking
mechanism keeps the return spring from driving the
motor actuator toward its return position during normal
reversible operation. The gear train and motor are
housed in an oil-filled compartment designed for
extended life.
The M100 provides the appropriate interface for a
variety of electronic controllers through selection of
factory-installed circuit boards. The M100 Series
Actuator is compatible with all Johnson Controls
controllers. The M100 can provide proportional,
floating, potentiometer, or on/off control, as well as
control by direct digital input from zone bus controllers.
The M100 Actuator requires a 24 VAC, 50/60 Hz power
supply; however, transformer options are available.
The actuator can be mounted for stem-up or
stem-down operation. On three-way valves, the seating
force can be applied on both the up and the down
stroke.
