Honeywell ML6421B1040 Direct-Coupled Valve Actuator

Honeywell ML6421A, B non-spring return electic linear valve actuators are used with low-voltage, single-pole, double-throw (SPDT), Series 60 two-position and floating controlling. They operatre standard Honeywell valves in HVAC applications. Features: Quick, easy installation on valves with 1 3/8-in. bonnet and 3/4-in. stroke, or with 1 7/8-in. bonnet and 1 1/2-in. stroke No required separate linkage and no adjustments required on linkage High force for VGF pressure-balanced valves Standard conduit connector Accurate valve positioning Low power consumption and high close-off ratings Force limiting end switches Synchronous motor The ML6421 Non-Spring Return Electric Linear Valve Actuators provide single-pole double-throw (spdt), Series 60 two-position and floating or modulating control to operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications. The modulating actuators accept an analog output of 0 to 10 Vdc or 2 to 10 Vdc, and an internal selector plug can be used to reverse the direction of action.
