Initial Inspection

Ensure product specification on nameplate and wiring

diagram matches the application and order.

Check actuator for any physical damage that may have

occurred during shipment.

If there are any discrepancies, contact your Triac

distributor to solve the problem immediately.

Terminology

Standard actuator direction and position references are

as follows.

Close = Clockwise

Open = Counter-clockwise

For the sake of this document, these terms may be used

interchangeably.

4. Information and Features

The WE, SE, XE and XC series electric actuators are for

use on quarter-turn valves and dampers requiring

between 690 to 25900 in-lbs of torque to operate.

Actuator positioning is achieved by travel limit switches

that disconnect power to the motor when engaged by

cams attached to actuator output shaft. A thermal

protector switch is built into the motor windings to

automatically disconnect the motor power if the motor

temperature exceeds the motor rating. Torque switches

are included on all actuators, except -690 size, as a

safeguard to prevent stalling and overheating the motor.

The ratio of the motor and gear train determines the

actuator speed and utilizes two worm gear sets to

transfer the motor torque to the output shaft. The double

worm gear configuration prevents the load from back

driving the output shaft. Accurate positioning is achieved

by the indicator cam shaft connecting directly to the

output drive.
