EL SERIES ACTUATORS :
EL actuators use worm and worm-wheel
reduction gearing to provide tight positioning control and the
self locking feature necessary for controlling larger valves,
particularly butterfly types.
The housing is of aluminium castings, it contains the drive
motor and worm gear assembly, together with the anti-condensation
heater and main terminal strip.
EL actuator take
the full range of control options, it has mechanical end position
stops and torque switches. Visual position indication is by
a window in the top cover.
A geared manual
override is fitted as standard, it is engaged by means of
a declutching lever. When the motor is energised the unit
automatically returns to motor operation, thus ensuring operator
safety.
These actuators are available
for ON / OFF and modulating applications.

ELS SERIES ACTUATORS
:
A compact, robust
range of Electric Actuators.
Especially designed
for small two and three way ball valves and similar drives
requiring 900 or 1800 of rotation from
a single phase or DC, electrical supply.
The water
tight, aluminium alloy housing with steel cover, contains
the drive motor and spur gear box assembly together with anti-condensation
heater and main terminal strip. Two limit switches provide
for position limiting remote position indication, space is
allowed for two extra switches or a potentiometer for additional
position feed back.
ELQ SERIES ACTUATORS
:
Series ELQ electric
Actuators are powerful, quarter turn units with five sizes
covering the torque range from 100Nm to 800Nm. They incorporate
High Ratio Drive (HRD) gearing which provides a compact backlash
free reduction gear ideally suited for both tight positional
control and long trouble free ON / OFF operation.Universal
power control allows direct connection to all the usual voltages.
The aluminium alloy
housing contains the motor, gear reduction and the Electronic
control unit (ECU) - Electronic control enables precise control
of the Actuators internal functions and a ready interface
to a wide range of control options. Electronic torque control
is included as a standard feature. Modular construction is
used throughout and allows for a wide range of "kit"
and "factory" options.
The manual override
handwheel is constantly engaged, it is non-rotating and arranged
so that at no time can be back driven by the motor. The handwheel
is removable for shipment, also to prevent local operation
when this is a requirement. The mounting / drive is to ISO
5211.
