INTRODUCTION
This installation and operating manual explains how to install, operate and maintain REA60 electric actuators.
Safety notices in this manual detail precautions the user must take to reduce the risk of personal injury and
damage to the equipment. User must read these instructions before installation, operating, or maintenance.
DANGER: Refers to personal safety. Alerts the user to potential danger or harm. The hazard or unsafe
practice will result in severe injury or death.
WARNING: Refers to personal safety. Alerts the user to potential danger. Failure to follow warning
notices could result in personal injury or death.
CAUTION: Directs the user’s attention to general precautions that, if not followed could result in personal injury
and/or equipment damage.
PRODUCT IDENTIFICATION
The actuator name plate is located on the top cover of the actuator.
The name plate contains the following:
TORK logo (trade mark)
Electrical power supply
Model
Type
Rated current
Operating time (seconds)
Serial No.
Option

Initial Inspection
Upon receipt of the actuator, inspect the condition of the product and ensure the name plate matches the order
sheet or your requirements, also check for any damage that may have occurred during shipment. If the wrong
product has been shipped immediately or is damaged report to the coordinator.
Storage
Actuators must be stored in a clean, cool and dry area. The unit shall be stored with the cover fastened and the
conduit openings sealed. Storage must be off the floor, covered with a seal dust protector.
When actuators are stored outdoors, they must be stored off the ground, high enough to prevent being immersed
in water or buried in snow.
GENERAL INFORMATION AND FEATURES
REA series electric actuators are designed to provide reliable and efficient operation of 90 degree quarter turn
valves , dampers, etc.

Duty Cycle
Duty cycle is rated IEC60034 - S4 50% / S2 30 min
Exceeding the actuators rated duty cycle may cause thermal overload.
Type of duty according to VDE 0530 / IEC 60034-1

Short - time duty S2
The operation time at a constant load is short, so that ther-mal equilibrium is not reached. The pause is
long enough for the machine to cool down to ambient temperature. The duration of the short - time
operation is limited to 15 min (10 min, 30 min).
Intermittent duty S4
The duty is a sequence of identical cycles which consist of starting time, operation time with constant load
and rest period. The rest period allows the machine to cool down so that so that thermal equilibrium is not
reached. The relative on-time at S4-25% or S4-50% is limited to 25% and 50% respectively .
Heater
Condensation in the actuator is possible due to wide fluctuation of the ambient temperature. The heater integrated
in the control unit prevents this in general.
Manual Hand Wheel and Lever
REA actuators are provided with a manual operation system.
The REA60 actuator comes standard with a manual override nut.
This is located on the bottom of the unit, and can be easily operated with a 5M wrench.
Turn the hand wheel until the valve reaches the required position.
Turn clockwise to open and counter clockwise to close.
When nut becomes tight DO NOT FORCE further as this will cause serious damage to the gearing.

Note: The override engagement lever returns automatically to auto position when the actuator is operated
electrically.
Lubrication
REA is a totally enclosed unit with a permanently lubricated gear train (Moly EP Grease). Once installed lubrication
should not be required. However, periodic preventative maintenance will extend the operating life of the actuator.

INSTALLATION INSTRUCTION
Pre-Installation (for use in General Services)
Verify the actuators name plate to ensure correct model number, force, operating speed, voltage and enclosure
type before installation and use.
It is important to verify that the output force of the actuator is appropriate for the force requirements of the valve
and that the actuator duty cycle is appropriate for the intended application.
WARNING: Read this installation and maintenance manual carefully and completely before attempting to
install, operate or trouble shoot the REA actuators.
Actuator Mounting
Note:
Prior to mounting the part-turn actuator it must be checked for damage.
Damaged parts must be replaced by original spare parts.
Mounting is most effectively carried out with the valve shafting pointing vertically upwards, however mounting is
also possible in any other position.
The REA series actuators are supplied with a Union Joint and nut which is removable for ease of machining.
CAUTION:
Do not attempt to work on your REA actuator without first shutting off Incoming power.
Do not attach ropes or hooks to the hand wheel for the purpose of lifting by hoist.
