RE Reversing Electronic NEMA 4/4X Actuators
On-Off, Tri-State, & Modulating Control, 150 in-lb to 10,200 in-lb

Model RE electric/electronic actuators are ideal for demanding valve applications and air damper control. The actuators are available with torque ratings from 150 in-lbs to 10,200 in-lbs. They incorporate current limiting as a means of protecting the actuator for over-torque situations and do not depend on torque switches or thermal overload sensing. The current limiting feature activates a light (and an optional relay) upon exceeding the current limit set, to allow for easy field diagnostics.

All actuators accept 24 VAC or VDC power and 120 or 220 VAC with the addition of a transformer. All actuators have field adjustable speed control as a standard feature. Actuators are designed for temperatures ranging from -40 °F to 150 °F (-40 °C to 65 °C). For temperatures below 32°F (0°C), outdoor applications, high humidity or wet locations the actuators can be supplied with an electric heater and thermostat.

All actuators shall have a solid state braking system, which works with or without power, (rated to 1-1/4 times the torque rating of the actuator). All units are equipped with a manual override, which will allow the actuator to be rotated in the clockwise or counter-clockwise direction. Optional solid cast aluminum override handwheels are available (spoked handwheels are not acceptable due to safety issues).

The actuator housing is a high strength aluminum casting with an exterior grade polyurethane enamel coating for excellent wear, corrosion, impact and UV resistance. The actuators are NEMA 4/4X type minimum. All cover fasteners are stainless steel. All actuators have a position indicator with the angle of rotation clearly marked. All actuators used in outdoor applications have white covers to lessen the solar heat load.

Model RE is capable of accepting 4-20 mA with 250 Ohms impedance, 0-10 VDC or 2-10 VDC signals. Input signal isolation is provided to isolate the input signal from the actuator power so that the signal and power can come from different sources, without the need for exterior isolation modules.

The Torque Maximizer permits Model RE actuators to operate at required torques
up to 10,200 in-lbs.It also allows the actuator to be mounted in applications with
space or location limitations.

The Torque Maximizer provides added gear reduction between the actuator and the
valve or damper, therebyincreasing the torque of the actuator. This product is 85%
efficient in transferring the torque from the input to output drive shaft. This unit
bolts directly onto the base of the RE actuator, then the combined actuator/gear
operator unit is mounted to the valve, damper or other application.
