Product features
For fail-safe, modulating control of dampers in HVAC systems. Actuator sizing should be done in
accordance with the damper manufacturer’s specifications. The actuator is mounted directly to
a damper shaft from 1/4” up to 1/2” in diameter by means of its universal clamp, 1/2” shaft
centered at delivery. A crank arm and several mounting brackets are available for applications
where the actuator cannot be direct coupled to the damper shaft. The actuator operates in
response to a 2 to 10 VDC, or with the addition of a 500O resistor, a 4 to 20 mA control input
from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for position indication.
The TF series actuators provide true spring return operation for reliable fail-safe application and
positive close-off on air tight dampers. The spring return system provides consistent torque to
the damper with, and without, power applied to the actuator. The TF series provides 95° of
rotation and is provided with a graduated position indicator showing 0 to 95°. The TF uses a
brushless DC motor which is controlled by an Application Specific Integrated Circuit (ASIC) and a
microprocessor. The microprocessor provides the intelligence to the ASIC to provide a constant
rotation rate and to know the actuator’s exact fail-safe position. The ASIC monitors and controls
the brushless DC motor’s rotation and provides a digital rotation sensing function to prevent
damage to the actuator in a stall condition. The actuator may be stalled anywhere in its normal
rotation without the need of mechanical end switches. Power consumption is reduced in holding mode.
Safety Note: Screw a conduit fitting into the actuator’s bushing. Jacket the actuator’s input and
output wiring with suitable flexible conduit. Properly terminate the conduit in a suitable junction box.
Spring return control damper actuators shall be direct coupled type which require no crank arm
and linkage and be capable of direct mounting to a shaft up to a 1/2” diameter and center on a
1/2” shaft. The actuator must provide modulating damper control in response to a 2 to 10 VDC
or, with the addition of a 500O resistor, a 4 to 20 mA control input from an electronic controller
or positioner. The actuator must be designed so that they may be used for either clockwise or
counter clockwise fail-safe operation. Actuators shall use a brushless DC motor controlled by a
microprocessor and be protected from overload at all angles of rotation. Run time shall be
constant, and independent of torque. A 2 to 10 VDC feedback signal shall be provided for
position feedback. If required, one SPDT auxiliary switch shall be provided having the capability
of being adjustable. Actuators with auxiliary switch must be constructed to meet the
requirements for Double Insulation so an electrical ground is not required to meet agency
listings. Actuators shall be cULus listed

MD Industrial Salvage often purchases entire inventories of high end Industrial, Electrical, Automation, Manufacturing, and PLC processing parts and supplies from businesses in transition. These could be factories, machine shops, distributors or stores that are moving, updating or closing. Although the businesses may no longer have any use for the items we purchase, they are sitting in the maintenance department or store room awaiting use. For the most part these inventories are generally new, and in the original package. Occasionally items we purchase are used, and placed on the parts shelf as backups, and will be listed as used on our listing. Some of the original packaging may have writing, shelf wear, tears or stains, but the product inside is in new condition, unless listed as used. We offer these items at a greatly reduced price off of wholesale and retail. We guarantee these parts and supplies to be new, unless noted, and in working condition. If it is used, it was placed in the parts area as a working spare and is ready, We offer a 100% return and refund policy, no questions asked, so bid with confidence!

About Us
Md Industrial Salvage is a different type of recycling company. We have operated in
Baltimore
and surrounding areas since 1996. After starting out rescuing fireplace mantles and cast iron door locks from construction dumpsters, we have opened our eyes to may types of waste that are often over looked and fall through the cracks. Our focus is, and always will be vintage items of the highest quality. But with our eyes now open we put a lot of effort in bringing you high end industrial and electrical parts as well. All our items are salvaged and are for the most part American Made. One week we could be in an old School or Brewery, the next week a Factory, and the following week and Shipyard or Power plant, you just never know. Also, one day we may be removing Vintage lighting, the next day Signs and Vintage blueprints and the following day cleaning out a machine shop or high end parts room. We literally have NO idea what we have coming around corner, so make sure you add us to your favorites and check back often.
