Actuator 24V

A 24V linear actuator for cab air flaps is used in heavy-duty trucks, buses and construction machinery, on the air-distribution flap that routes fresh, recirculated or demisted air into the cab and the equipment enclosure. It mounts on the duct housing by its front ears and pins to a short crank arm on the flap shaft: the rod extends, the crank turns, the flap opens. Thrust and travel are set by the flap area, the pressure across it and the crank-arm length.

Product Introduction

Product Introduction

 

The Actuator 24V  can be wired to the vehicle harness directly, with no 24-to-12 V converter to package inside the duct area. The unit is fixed to the duct housing by its front ears, and the rod end is pinned to a short crank arm on the flap shaft: extending the rod rotates the crank one way and retracting it turns the crank back, so the flap moves to a new opening position and stays there. The thrust and travel required are set by the flap area, the static pressure difference across it, the seal friction at breakaway and the length of that crank arm - not by the size of the duct.

Product Application

 

Industrial Automation Equipment

In production line automation systems, the Actuator 24V is primarily used for valve control, conveying devices, and robotic arms to achieve precise linear motion control.

 

Intelligent Door Control Systems

In electric doors, turnstiles, and window controls, the Actuator 24V is responsible for driving the opening and closing actions.

 

Medical and Home Equipment
Used in hospital beds, adjustable chairs, rehabilitation devices, etc., to perform height and angle adjustment functions.

 

Agricultural and Livestock Machinery
Used for automatic ventilation, feed door, or irrigation valve control to achieve automatic adjustment.

Certifications, Testing and Warranty

 

Each actuator is assembled and checked in our own ISO 9001 certified . Certificates and utility model patents are listed on the [Certification] page, alongside the [testing equipment] used for validation, and a CE declaration and RoHS documents come with the configuration you select. As a component supplier, we support the builder's machine with the test values and drawings it needs. Minimum order is one piece and the product carries a 6-month warranty - see [why customers work with KABASI].

FAQ

 

Can this actuator be connected directly to a 24V truck electrical system?

Yes. 24V DC is the standard configuration and matches the electrical system on heavy-duty trucks, buses and construction machinery; 12V DC is available on the same body. Tell us the supply window your harness delivers - a vehicle bus rises while the alternator charges - so the build is confirmed against it.

Does the flap keep its position when the ignition is switched off?

Yes. Static self-locking is more than twice the rated thrust, so the lead screw holds the last commanded angle with no current. If the duct needs the flap to fail to a specific position instead, that must come from the flap mechanism.

Is 2 kg (20 N) of thrust enough for my air flap?

Multiply the holding torque at the flap shaft by the crank-arm length, then add the breakaway peak; if that is above 20 N, the same platform is built at 8 kg and 20 kg. Send the flap drawing and we will size it.
