Description

Description
Eaton's Flat Actuator is designed to operate valves that require 90 degrees of movement to the open and closed positions. The unit consists of a 28 Vdc (nominal) permanent magnet motor and a worm/spur gear arrangement to produce the rotational movement. Travel limits are controlled by position control microswitches. Positional indication is provided by independent microswitches. A ‘see/feel’ indicator at the end of the output shaft can be seen or felt to establish the valve position.

Design Features
• The Flat Actuator can be used to drive in-line valves, pedestal mounted valves or remotely driven valves. It can be attached to the required valve/drive unit by two captive socket head M5 bolts.

• An epicyclic gearbox can be installed within the unit to provide a reduced operating time and increased torque capability. A unit with this feature is used on the Nimrod
MRA4 maritime patrol aircraft.
