electrical actuator

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 energized 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 hand wheel is constantly engaged, it is non-rotating and arranged so that at no time can be back driven by the motor. The hand wheel is removable for shipment, also to prevent local operation when this is a requirement. The mounting / drive is to ISO 5211.

Notes:
Stall protection through electronic torque switches.
Limit Switches-(2 nos.), heater, manual override and position indicator are available as standard for all models.
Duty rating 100% for actuator model ELQ.
