Introduction
Product Description
The Eclipse T500 Actuator is suitable for driving flow
control valves, butterfly valves, dampers or other
applications which require rotary motion.
The Actuators are primarily used with an electronic
controller to regulate a process load, such as
temperature. Models provide proportional positioning in
response to 2-position, 3-position, 135 ohm, 4-20 mA and
2-10 VDC signal.
The drive shaft of the actuator connects
to a butterfly valve stem, which rotates 90 degrees from
minimum to maximum position.
