Description
The Series 72 Modutrol IV Motors spring return and non-spring return motors are used to control dampers and valves. The motors accept a current or voltage signal from an electronic controller to position a damper or valve at any point between open and closed.

Features
  • Integral spring return returns motor to normal position when power is interrupted.
  • Integral junction box provides NEMA 3 weather protection if motor is mounted in the upright position.
  • Motor and circuitry operate from 24 Vac.
  • 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 degrees).
  • Integral auxiliary switches are available factory mounted, or can be field added.
  • Spring return motors can operate valve linkages from 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.
  • Fixed torque throughout the entire voltage range.
  • Motors are designed for either normally open or normally closed valves and dampers.
  • Models available with adjustable start (zero) and span.
  • Models available with 4 to 20 mA input signal.
  • Models available with 2 to 10 Vdc input signal.
  • Die-cast aluminum housing.
