Honeywell MT4000A2027 (Modutrol IV) servo actuator. Electric actuator 45 Nm for controlling air dampers, gas valves, and rotary mechanisms in boiler rooms and HVAC systems. Honeywell MT4000A2027 (Modutrol IV series) is a professional electromechanical actuator (electric motor with gearbox) designed for precise positioning of burner air dampers, VF5000 rotary dampers, 3-way valves, and other devices requiring smooth or positional control. The MT4000A2027 servo actuator is typically used in boiler rooms and building automation systems (HVAC) to regulate air supply (on burner damper), flue dampers, fuel valves, or to actuate mixing valves. If your boiler equipment does not reach power, overheats, or gives an error regarding the air damper position, the cause may be a faulty servo actuator. Technical specifications: Parameter Value.
