Honeywell MS4103A1130 S/R Direct Coupled Actuator 45 Sec 120-230V

The Honeywell MS4103A1130 S/R Direct Coupled Actuator is an electric actuator that mounts dampers and valves to control the flow of air and fluids in HVAC systems. It uses a 120-230 VAC supply, and a 45-second stroke time, which gives a steady torque to control elements to be modulated. It is designed to be directly coupled to shafts without any extra linkages and is installed on zone dampers, mixing boxes or hydronic valves in residential and commercial heating and cooling units.
