VG1000 Series Forged Brass Ball Valves Product Bulletin 39
Electric Actuator Control Signal Action
Two-way VG1000 Series Ball Valves are fully open
when the electric actuator is fully Counterclockwise
(CCW) and fully closed when the electric actuator is
fully Clockwise (CW). For three-way valves, the Port A
and common port are fully open when the electric
actuator is fully CCW, as shown in Figure 5. Port B and
common port are fully open when the actuator is fully
CW, as shown in Figure 6.
Note: VG1841 and VG1845 three-way ball valves
have a different port configuration (as shown in
Figure 5 and Figure 6) from the older VG1644 Series
three-way ball valves (Figure 7), and you must change
the piping to convert them to the new series of valves.
For non-spring return and spring-to-open proportional
control models in the direct-acting mode, a minimum
control signal drives the electric actuator to the fully
CCW position, whereas a maximum control signal
drives the electric actuator to the fully CW position.
For spring-to-close proportional control models in the
direct-acting mode, a minimum control signal drives the
electric actuator to the fully CW position, whereas a
maximum control signal drives the electric actuator to
the fully CCW position.
For non-spring return floating or on/off (floating) control
models, a control signal to Terminal 2 (or wire 2) of a
VA9104 or an M910x Series Actuator drives the electric
actuator to the fully CW position. Likewise, a control
signal to Terminal 3 (or wire 3) of a VA9104 or an
M910x Series Actuator drives the electric actuator to
the fully CCW position.
A control signal to Wire 3 of side A mounted (away
from the valve) VA9203 or VA9208 Series actuated
spring-to-open floating control valve assembly drives
the electric actuator to the fully CW position. Likewise,
a control signal to Wire 4 of a floating CCW-face
VA9203 Series or VA9208 Series Actuator, or removal
of the control signal from Wire 3 of an on/off CCW-face
VA9203 Series or VA9208 Series actuated spring-to-
open valve assembly, drives the electric actuator to the
fully CCW position.
A control signal to Wire 3 of a CW-face (mounted away
from the valve) VA9203 Series or VA9208 Series
actuated spring-to-close floating control valve
assembly drives the electric actuator to the fully CCW
position. Likewise, a control signal to Wire 4 of a
floating CW-face VA9203 Series or VA9208 Series
Actuator, or removal of the control signal from Wire 3 of
an on/off CW-face VA9203 Series or VA9208 Series
actuated spring-to-close valve assembly, drives the
electric actuator to the fully CW position.
Electric Actuator Selection
VG1000 Series Ball Valves are designed for factory or
field mounting to a variety of M9000 and VA9000
Series Actuators. VA9000 Series Actuators include all
hardware necessary for attachment to the valve.
M9000 Series Actuators require an additional linkage.
See Table 36.
