Overview The Non-Spring Return Electric Linear Valve Actuators have floating or modulating control. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications. Floating control actuators are used with controllers that provide a switched or floating single-pole double-throw (SPDT) output. Modulating control actuators are used with controllers that provide an analog output of 0 to 10 Vdc or 2 to 10 Vdc. Features Easy and quick installation on valves with 1 3/8 in. bonnet and 3/4 in. strokeNo separate linkage requiredConduit connector standardNo adjustments required on linkage. Accurate valve positioningLow power consumptionHigh close-off ratingsForce limiting end switchesManual operatorSynchronous motorMaintenance freeML7420 has an internal selector plug that can be used to reverse the direction of action.
