M954, M965, and M975 motors.
• Integral junction box provides NEMA 3 weather
protection.
• Integral spring return returns motor to normal position
when power is interrupted.
• Motor and circuitry operate from 24 Vac. Models
available with factory installed transformer, or a field
added internal transformer.
• Quick-connect terminals are standard-screw terminal
adapter is available.
• Adapter bracket for matching shaft height of older
motors is available.
• Motors have field adjustable stroke (90° to 160°).
• Die-cast aluminum housing.
• Integral auxiliary switches are available factory
mounted, or can be field added.
• Nominal timing standard of 30 seconds (90° stroke),
and 60 seconds (160° stroke). Other timings available.
• Spring return motors can operate valve linkages form
power end or auxiliary end shafts for normally closed
or normally open valve applications.
• All models have dual shafts (slotted and tapped on
both ends).
• All models have auxiliary switch cams.
