Linear Actuator HC-09140
Hays Cleveland Series 9140 Linear Actuators offer long life, safety, reliable operation, and easy maintenance. These compact units are available with a full range of options for maximum flexibility in any combustion control or process control application.
- Compact, flexible design is suitable for combustion and process control applications.
- Stepping motor stops and starts instantaneously: eliminates coast and provides precision positioning.
- High starting torque overcomes static friction.
- Impedance-protected motor is not damaged if overload stalling occurs.

Series HC-9140 Linear Actuators accept electrical line voltage signals from a switched output controller to position a final control element, such as a damper, control valve, louver, stoker lever, variable speed transmission, or any similar device, over a six-inch range of travel.
Hays Cleveland Series HC-09140 Linear Actuators require no mechanical brake assembly. The inherent braking-action of the synchronous stepping motor prevents overtravel without the wear and stress associated with friction or “DC” braking. As shown in the Specifications section of this bulletin, two stroke times and thrust ranges are offered for all models.
- Compact, flexible design is suitable for combustion and process control applications.
- Stepping motor stops and starts instantaneously: eliminates coast and provides precision positioning.
- High starting torque overcomes static friction.
- Impedance-protected motor is not damaged if overload stalling occurs.
- Standard 6” range of travel.
- 30 and 60 second nominal stroke times.
- 75 and 150 lb. thrust ranges. Equivalent to 18.75 and 37.5 lbs.
- Operates on switched line voltage input.
- Optional handwheel.
- Optional feedback potentiometer for remote position indication.
- Optional adjustable “safe start” position switches.
- Includes integral adjustable start switches wired to interface with Hays Cleveland Series 7720 draft controllers.
The line voltage signals control the reversible motor in finite increments to drive an acme screw through a nonslip timing belt drive and pulley system. The screw drives through a travel nut-and-bearing arrangement to extend or retract the drive tube. The nut and screw assembly self-locks in the case of power failure, in order to maintain final drive tube position.
End switches shut off power to the motor when the unit reaches either the inward or the outward travel extreme.
All applications use the full six-inch travel of the drive arm. Linear or nonlinear movement of the final control element, as well as its total range of travel, is controlled by adjustment of the linkage connecting the actuator’s drive arm to the operating lever of the final control element. Overload stalling will not damage the motor.
Hays Cleveland Series 9140 Linear Actuators can be mounted in any position on any flat, rigid surface free from excessive vibration. All wiring connections are easily accessible for maintenance. The ambient temperature limit is 140F (60C).
