S4 Series
Multi-voltage Reversible Electric Actuator
The S4 Series is a 1/4 turn multi-voltage electric
valve actuator which incorporates the latest
advances in motor and control technology at an
economical price.
S4 SERIES
MODEL NUMBERING
The S4 unit incorporates automatic voltage sensing
and allows for AC or DC supply within each voltage
range. The electronic torque limiter protects the
actuator and the LED status lights allow for easier
field diagnostics. The domed position indicator
provides a visual indication of valve position. The
DIN wiring connections allow the unit to be field
wired without opening the actuator.
Output Torque:
0170 = 170 in-lbs
0300 = 300 in-lbs
0480 = 480 in-lbs
0750 = 750 in-lbs
1200 = 1200 in-lbs
2600 = 2600 in-lbs
Options include a plug-and-play analog to digital
positioner and a battery “spring return” feature
that allows the actuator to fail closed or fail open in
the event of a power failure.

isolated dry contact switches to cut the power to the motor,
otherwise the actuator will not reach the full open or full

S4 Series
Multi-voltage reversible electric actuator
(12 to 24 VAC/VDC and 85 to 240 VAC/VDC)
S4 LED STATUS INDICATOR
Constantly Lit LED:
If the actuator is operating correctly with no faults, the LED shows a constantly lit light.
LED Flashes with Two Blinks:
If the actuator has been left in “manual” mode, the actuator’s motor runs but doesn’t drive the
output shaft. After a preset time, the actuator knows that as the torque limiter has not activated
and that the motor is running, it must be in manual.
LED Flashes On/Off:
When the actuator senses an inpending valve jam, the electronic torque limiter is activated, and on
activation, repeatedly flashes the LED on and off.
ACCESSORIES
Electronic Positioner:
The DPS is a microprocessor based electronic positioner that takes an analog input (4-20mADC or
0-10VDC) and provides an analog output (4-20mADC or 0-10VDC). The positioner is self-calibrating
upon start up or after the valve is positioned manually. The DPS circuit is continuously monitoring
the input and output signals and the physical position. Digital control insures high sensitivity and
repeatability. The positioner can be installed in the field.
Battery Failsafe:
The BSR option is a battery “spring return” capability that allows
the actuator to fail open or fail closed upon loss of power. This
option is significantly smaller and cost competitive when compared
to mechanical spring return electric actuators. The battery is
constantly charging so it has maximum capacity when needed.
It provides the power to close or open the valve a few times upon
loss of power. If you plan to use the actuator to replace a
solenoid; energize to open, fail close, you will have to allow a
short period to charge the battery back to maximum power
between cycles. A positioner can be installed with the BSR option.
Optional DIN Connectors:
DIN connectors are available with a 15’ cordset or with 1/2” NPT
conduit entry.
