Barber actuator Direct Coupled Damper Actuators Flat Pack Series
The flat pack series is UL/cUL listed and CE compliant. It is also NEMA 4 (IEC IP56) compliant when used with customer supplied water tight conduit connectors. Units are available to operate from 24Vac (class 2) and 120Vac and 240Vac (class 1). The Flat Pack Series are direct-coupled actuators used for damper control applications. They are available in spring return and non-spring return models, with two-position control. They may be specified to be either analog proportional control action or floating proportional control action.   Flat pack series actuators are mounted directly onto the damper shaft by means of dual mounting clips. The anti-rotation bracket supplied with the actuator prevents lateral movement of the actuator on the shaft. The damper actuator is not provided with and does not require any limiting switches. It is electrically protected against overloading. The angle of rotation is electrically limited to 93 ± 1°. When reaching the damper or actuator end position, the motor stops automatically. The position of the actuator is indicated by means of an integral scale reading 0º to 95°.   EA02-P Series  This actuator is available

Barber Linear Actuator EA81 Proportional Hydraulic
The Model EA81 is a hydraulic valve actuator with a linear stroke for proportional control of small valves that require return to normal position on power interruption. The permanently sealed oil-filled case contains a moveable hydraulic system. The electric pump/motor, powered continuously by the input supply voltage, generates fluid pressure opposed by the spring of the damper or valve linkage. The EA81 is available in two models, a 4-20mAdc input and a 135 Ohm slidewire input.   The control signal is compared to measured shaft position in the actuator controller circuit and the output generates proportional positioning of the valve shaft. The unit supplies a force of 150 pounds for a linear stroke and operates on 120Vac, 50/60 Hz. The linkage kit and extension, model AV-611, provides linkage to 1/2" to 1-1/4" valve sizes. The EA81 is compatible with the VB-7000 valves in this catalog.       FEATURES: DCmA or slidewire inputs Spring return on power interruptiont 120Vac, 50/60Hz operation 150 pounds force, linear stroke Compati

Barber Non-Spring Return Linear Actuators MF Series Direct Coupled
Floating Proportional Actuator  The direct coupled Model MF-63103 and Model MF-63123 floating proportional actuators connect directly to our VB-7000 Series valves and may be connected our Series VB-9000 valves as well as other commercially available valves either directly (1/2" to 2" valves) or through the use of available linkage kits (2-1/2" to 4" valves). This non-spring return actuator may be controlled by the SPDT contact or triac output of a controller capable of providing drive open, hold and drive close outputs. It is available with an SPDT optional auxiliary switch, adjustable over the actuator stroke of one inch and factory set for the NC contact to make at 3/8" from fully extended position. Actuator features include 1/2" Stainless Steel jackscrew, roller thrust bearings and an all-metal gear train. It accepts a 24Vac power input.   The MF Series is compatible with the VB-7000 and VB-9000 valves in this catalog.     Proportional Analog Control Cards  The Model MF-63123 actuator can receive an optional analog module card allowing it to accept either a mAdc or Vdc signal from a controller. These cards plu

Barber Non-Spring Return Rotary Actuator EA20 Standard Series Low Torque
Working in conjunction with primary loop controllers, these low torque non-spring return actuators will proportionally position fuel valves, butterfly valves, dampers or other similar devices. The output shaft moves in both directions and can stop at any point in the stroke. The hardened steel crankshaft is driven through a train of precision hobbed gears sealed in oil. This reliable actuator is driven by a shaded pole motor completely submerged in oil and sealed in an aluminum case, minimizing maintenance.   Four models are available featuring a standard 100ž internal feedback slidewire and a selection of travel time and rotation limit. Not available with end limit switches, some models have auxiliary switches and a variety of optional features. The EA-20 Series are UL and cUL or CSA listed, except for models with built-in transformers. CSA listed models are: EA21-00003-000-0-00, EA22-00000-000-0-00 and EA24-00000-000-0-00. It is compatible with the VB-7000- and VB-9000 valves in this catalog.         FEATURES: Proportional actuat

Barber Non-Spring Return Rotary Actuator EA31
The Model EA31 actuator is a non-spring return gear driven crankshaft actuator for two position operation of dampers, valves or other equipment that doesn’t require return to normal position upon power interruption. The hardened steel crankshaft is driven through a train of precision hobbed gears. The actuator is driven by a shaded pole motor that is completely submerged in oil and sealed in an aluminum case to assure long life and minimum maintenance. The gear train of the EA31 crank actuator is also sealed in oil.   Working in conjunction with primary loop controllers, these power units are ideal for ON-OFF control of valves and dampers. The EA31 travel time is 30 seconds and its shaft rotation is a unidirectional 180º clockwise stroke from 0-180º or clockwise from 180-0º. The Model EA31-00000-00-0-00 is UL/CSA listed. All other models are UL/cUL listed.
