24V Non-Spring Return Foot Mounted Actuator, 300 lb-in.

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.
