Actuators, Valves & EA Motors
Standard EA Series Rotary Actuators
The standard EA series of actuators contains both gear driven crankshaft and hydraulic powered axial shaft actuators. They may be used with combustion air dampers and a wide variety of low, medium and high torque rotary shaft valve bodies with crankarms. The EA series can accommodate applications requiring position to be held or returned to normal position during power interruptions. Used for two position floating and proportional electric control, these actuators are employed wherever it is desirable to move a load in either direction or to stop it at any point in the stroke. Eight base models plus variants are included in the complete product range, offering a variety of control action, motor voltage and frequency, torque, return action and optional features.

EA series actuators are well known for their robustness and quality of manufacture. Many models are NEMA 4, UL/cUL or UL/CSA and are made to operate in heavy-duty applications in severe environments. Mechanical features include high quality die-cast aluminum housings with conduit knockouts and reliable oil immersed motors and hobbed gear trains. Most models include an auxiliary switch as standard.

EA12 Valve Actuators
The Model EA12 actuator is a spring return gear driven crankshaft actuator for two position operation of dampers, valves or other equipment that 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 EA12 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 EA-12 travel time is 20 seconds and its travel limit is 170 degrees clockwise. The spring return is counterclockwise to the original position when de-energized. The Model EA12-00000-000-0-00 is UL/CSA listed. All others models are UL/cUL listed. The EA12 is compatible with the VB-7000 and VB-9000 valves in this catalog.
- Spring return two position operation
- 60 in-lbs torque - 20 sec travel
- Oil immersed motor and gear train
- Compatible with VB series valves
EA20 Valve Actuators
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 100 Ohm 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.
- Proportional actuators with built-in feedback potentiometer
- Open/Close contact closure input
- 240/120/24Vac models available
- 50 in-lbs torque, optional NEMA 4
- Compatible with VB Series Valves

EA40 Valve Actuators
The EA40 spring return actuator, will proportionally position a fuel valve, butterfly valve, damper and other similar devices.
The output shaft is power operated in both directions. An internal electrical holding circuit maintains the proper damper position at setpoint. The enclosed spring drives the output shaft and gear train to return the damper to a normal position on power interruption.
Standard features include 100 ohm internal feedback slidewire and single internal SPDT switch. All models are UL/cUL listed. The EA40 is compatible with the VB-7000 and VB-9000 valves.

- 50 in-lbs torque
- Compatible with VB series valves
EA50 Valve Actuators
The EA50 and EA60 medium torque actuators are ideal for proportional positioning of a fuel valve, butterfly valve, damper and similar applications. Units are available with either fixed or adjustable speed. Timing of adjustable speed units can be increased (decreasing the speed) by turning a slotted adjustment screw on the outside of the case. Adjust range is approximately ten times rated. Standard features include a 100 Ohm feedback slidewire and a single SPDT switch. All models, except those with transformers, are UL/cUL listed. The EA50 and EA60 are compatible with the VB-7000 and VB-9000 valves.
- Proportional actuators w/ built-in feedback potentiometer
- Open/Close contact closure input
- 24Vac, 120Vac, and 240VAC

EA70 Valve Actuators
EA70 Series Valve Actuators are ideal for Heavy dampers, globe valves, blast gates, air/gas valves.
These workhorses have the brute force to handle the big job such as a heavy damper, globe valve, blast gate or air/gas valve. It can be used for vortex control and hydraulic coupling and will drive a speed changing screw or slide gate re-quiring a torque proportional actuator. A solenoid brake holds the actuator in position when no movement is required. These actuators stay in position when power is removed. NEMA 4 versions are available. The EA70-A is compatible with the VB-7000 and VB-9000 valves.
