60 lb-in Two-Position Modutrol IV Motor, 120V
• Fixed torque throughout the entire voltage range.
• Integral spring return returns motor to normal position in the event of power failure.
• 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).
• Motors are designed for either normally open or normally closed valves and dampers.
• Integral auxiliary switches are available factory mounted, or can be field added.
• Motors can operate valve linkages from the 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).
Overview | Series 41 and Series 81 Modutrol IV motors are 2-position (line- and low-voltage per motor control) spring-return motors. They are used to operate dampers or valves in applications where it is necessary or desirable to have the controlled element return t |
