Description
Type EL electric actuators use worm and wormwheel reduction gearing to provide tight positioning control and
the self locking feature necessary for controlling larger valves, in particular butterfly valves.
CLOSED
The housing consists of an aluminium base casting and a steel cover, this contains the drive motor and worm
gear assembly, together with the anti-condensation heater and main terminal block.
Manual
Operation
EL actuators take the full range of control options, they have handwheel geared manual overrides, mechanical
end position stops and position indication by a raised dome in the top cover.
