Microelectric Actuators
CE certified
Automatic alignment
Manual control with position indication
Remote control by contact closures or
TTL logic level signals
RS-232 bidirectional communication (optional RS-485)
Two position and selector versions
Universal power supply, 110/230 VAC to 24 VDC
The microelectric actuator offers Valco
dependability in a unit which is less
than half the size of our standard
model. The actuator consists of a
control module, a stepper motor/
gearbox assembly, a manual remote
control, interconnecting cables, and a
110/230 VAC to 24 VDC power supply.
The composite version combines the
stepper motor/gearbox assembly
with the control module. The RS-232
interface cable, if required, must be
ordered separately.
Since different valve models have
varying actuation torque requirements,
there are five microelectric actuator
models for two position valves – EQ,
EH, EP, ED, and ET – and two versions
tech tip
Electric actuators can
be directly controlled
by signals from
microprocessor-based
instruments, data systems,
or valve programmers,
unlike air actuators, which
require an interface to
convert the signal to an
air pulse.

Consult the chart on the respective
ordering information page to
determine which model meets your
requirements. When a valve and
actuator are ordered at the same
time, the proper actuator is supplied
automatically.
An actuator can be specified with
closemount hardware, with a standoff,
or with just the standoff mounting
hardware, if your valve already has a
standoff. The microelectric actuator is
designed for room temperature use.
Valves which will be mounted in ovens
require a standoff assembly, which
locates the actuator out of the heated
zone.
