LINEAR ACTUATORS
Specification no. 477-X-XXX
†
Satchwell Linear Actuators type 'AL' are reversing actuators having a
linear output, for direct coupling to Satchwell lift and lay seat-type
control valves or other seat valves requiring a linear driver over stroke
lengths of up to 38mm (1½"), within the limits of output thrust stated
overleaf and with compatible mounting arrangements.
These actuators are suitable for either two-position or modulating
control, dependent on the controller or other switching device providing
the input signal. The ALM is suitable for a mains power supply, the ALX
is 24V, and the ALE is 24V, but accepts a 0-10Vdc input signal.
The ALE actuator can be set to operate a low hysteresis when used for
tight control applications on microprocessor based controllers such as
the KMC and MMC.
FEATURES
• Direct coupling to Satchwell seat valves without extra
mounting brackets or linkage kits, saving site time
• Direct coupling to other makes of seat valves, where stroke,
thrust and mounting are compatible
• Universal for valve strokes, up to 38mm (1½"). Actuator stroke
is self-setting to suit valve stroke, including ALE by simple
adjustment
• Alternative stroke times, to suit application
• Manual operation or override facility built-in
• Standard or low hysterisis selection on ALE to cater for
different application types
• Case sealed to IP 54 as standard
• Auxiliary switch kit available, see 'Accessories'
† For the full specification number replace the 4Xs with the
appropriate figures from the 'TYPE' column in the table
on page 2.
