By offering mechanical power to different items attached to your system, HVAC actuators can provide functionality in a way that no other part can. Modulating devices, damper controls, and countless other system parts require these motors to experience any motion. Generally, they're overengineered and typically boast long service lives. That means they can be replaced infrequently and should prove capable of standing up to the kind of usage seen in commercial settings.

Eventually, you will need to replace some actuators attached to the system. When that time comes, our team here at Furnace Part Source has prepared a collection of parts that should be compatible with a comprehensive market subsection.

Compatibility Options For HVAC Actuators

Every so often, manufacturers discontinue one of their actuator designs and replace it with something more modern. That's why HVAC technicians need to keep abreast of all of the changes in the industry. 

Belimo

Belimo's current offerings, such as the 24-volt NMB24-3 and TR24-SR-T modules, are designed to replace older models that have fallen by the wayside. Standard LF24-SR actuators are also offered in a convenient 24-volt configuration. While it might sometimes be concerning to hear that a part has been discontinued, this should help to alleviate any issues.

Torque Functionality

All three modules provide sufficient torque to maneuver whichever nodule they're connected to in a device. Technicians who swap out a faulty model should find that their new replacement either meets or exceeds the initial specifications of the device. 

More than just a nice feature, this kind of functionality is vital. You must always ensure that the overall pressure applied is only as significant as what the original equipment manufacturer intended.

When you want to find out what kind of actuator motor you need, you have to look for a specification number stamped or printed onto the housing. It's typically located close to the terminal ingress point, where the shaft comes out of the rest of the motor. 

Once you've found this number, you should know the kind of actuator you're working with within a furnace. Several styles are typically deployed in residential and commercial-grade configurations, so you'll want to familiarize yourself with these.

Types Of HVAC Actuators In Use

Proportional and stepped actuators have traditionally been the most common types found on the market. Incrementally stepped designs are older and usually only allow HVAC technicians to select between one of several different settings. 

More modern proportional devices give the operator a complete set of analog controls, which in turn helps run the equipment as efficiently as possible. Installers putting HVAC systems in wholly new buildings will have the luxury of selecting whichever option best fits their configuration.
