Worcester Actuation Systems
Worcester Controls Series 75
A time-tested, high-quality state-of-the-art electric actuator for remote control of quarter-turn valves and
other rotary devices. Simple, compact and reliable.
Series 75 Electric Actuators from Worcester Actuation Systems add a
new dimension of operational dependability and flexibility to modern
processes controlled by computers, programmable controllers and
other electric control equipment. A multi-function capability permits use
of the Series 75 actuator throughout the process for on/off, throttling,
variable-cycle and any analog or digital control. One of the most reliable
electric actuators on the market, the Series 75 is lightweight, compact
and powerful. Its split phase capacitor AC reversing motor or DC motor
drives a valve through a sealed, permanently lubricated gear train which
offers virtually lifetime maintenance-free dependable operation.
The Series 75 is available in eight sizes and produces torques to 3000
in-lbs. Housings are designed to TYPE 1 General Purpose, TYPE 4
2
Watertight, and TYPE 7, Class 1, Division 1 and 2, Group C, D and
TYPE 9, Class II, Division 1 and 2, Group E, F, G. A combined location
TYPE 4, 4X, 7, 9 enclosure is also available as a “Z” option. A baked
polyester finish is the standard coating, but special coatings are available for extreme hazardous-environment applications.
Series 75 actuators may be used on Worcester Controls complete line
of ball valves, other quarter-turn valves or devices requiring rotary
operators. Moreover, their ability to provide power in both directions
through selected arcs from 20° through 300° makes them ideal for
control of heating, ventilating and air conditioning duct systems and
automatic, remotely operated equipment.

Options to Fit Your Applications
The Series 75 can be ordered with a variety of options to tailor it to
the needs of your application.
Cycle Length Control – This speed control feature allows field adjustment of opening and closing cycle times, 19 minutes for 25% duty
and 57 minutes for 75% duty actuators.
Feedback (0-1000 ohm) Potentiometer – provides a variable resistance to signal the exact position of the output shaft and the valve it
is powering.
TYPE 4
Sizes 10, 12, 15, 20, 22
(Enclosure Option – W)
Position Indicator Board – provides a 4-20 mA valve position feedback
signal to the control room.
Heater/Thermostat – prevents condensation from collecting inside the
actuator.
Condensation Drain Plug – drains accumulated water.
180° Center-Off Kit – provides an extra position for three-way valves
and is used for dribble-feed applications in quarter-turn valves.
TYPE 1
Sizes 10, 12, 15, 20, 22
(Enclosure Option – Blank)
Additional Limit Switches – may be used to operate lights that indicate valve position or to operate other equipment.
AF-17 Positioner Board – for control valves positions the actuator
based on an input signal of current, voltage or resistance.
DFP17 DataFlo P™ – is a microprocessor-controlled electronic positioner with software for on-site or remote operation and diagnostics.
This new, smart positioner for Series 75 actuator driven control
valves is controlled by a 4-20 mA analog signal from a PLC or digitally from a computer.
DFC17 DataFlo C™ – is a microprocessor based PID single-loop controller that accepts a variety of process inputs. All process parameters
are easily programmed through the keypad or via a simple RS-485
computer interface.
I 75 Low-Current Circuit Interface – is a solid-state interface/relay
between the PC/controller/computer and actuator motor(s). It protects controlling device outputs from destructive feedback. This
high-voltage feedback is due to limit switch action, auto transformer
effect of unused winding, and capacitor voltage. The unit, as a printed
circuit board, is conveniently mounted inside of standard enclosures.
Maximum output ratings are 4 A for 120 VAC and 2 A for 240 VAC.
Controllers with outputs that have low current ratings cannot be connected to electric actuator motor(s) that require a current greater than
the controller rating.
R 75 Remote Terminal Unit (RTU) – is an interface for DC powered
actuators. This solid-state interface card allows you to control a DCpowered electric actuator by a control signal from the Remote
Terminal or any low current system (such as a solar powered system). It is equipped with a field-adjustable current limiting circuit,
which will trip the power in case of abnormal conditions (it will reset
by reengaging the control signal). Optional contact closure to indicate
the tripped condition; 0-5 VDC, 0-1000 ohm position feedback, and
end of travel SPDT gold contact switches are available.

Actuator Sizing
There are a few terms associated with electric actuators that
require definition. Actuator Start-up Torque is the amount of
torque initially produced by an actuator when starting from
rest. Use start-up torque when sizing an electric actuator for a
ball valve that is used for either on/off or throttling service.
Actuator Stall Torque is the amount of torque produced by the
actuator just prior to the point where the motor stalls. Do not
use stall torque for sizing.
OVERCURRENT PROTECTION WARNING!
Where overcurrent protection is used in the actuator power
circuit, it is recommended that the protection rating not be
less than the values listed in the table:
