Used within heating, ventilating, and airconditioning (HVAC) systems to drive a variety of quarter-turn, final control elements requiring spring return fail-safe operation.

Designed to meet both UL-555 and UL-555S safety requirements at 250⁰F for fire and smoke applications.

The MS4104, MS4109, MS4604, MS4609, MS8104 and MS8109 are spring return direct coupled actuators (DCA) for Fire and Smoke dampers.

The MS4120, MS4620, and MS8120 are spring return direct coupled actuators (DCA) for Fire and Smoke dampers.

Honeywell MVN Series Control Valve Actuators are designed to be used with VBA16P and VBA16F Series Ball Valves. Actuators can connect to external auxiliary switch. There is an overload for protection MVN Series Control Valve Actuators.

Honeywell MVN Rotary Valve Actuators are used to control hot and chilled water with glycol solutions up to 50% in heating, ventilating, and air conditioning (HVAC) systems to provide two-position or modulating functions.

Modmotor Accessories, Modutrol Motor

The OM series is equipped with standard modulating (4-20mA, 1-5V, or 0(2)-10V select by DIP-switch) control quarter-turn electric actuator. The OM series can also provide feedback output signal.

Series 90 Modutrol IV™ Motors are spring return and non-spring return modulating proportional control motors. These motors are used with controllers that provide a Series 90 output to operate dampers or valves.

Series 61 and Series 62 Modutrol IV™ Motors are 3-wire spring return and non-spring return floating control motors.

Series 71, 72, and 76 Modutrol IV™ Motors are spring return and non-spring return motors used to control dampers and valves. The motors accept a current or voltage signal from an electronic controller to position a damper or valve.

Direct-Coupled Damper Actuators by MK Electric are provides modulating and floating/2-position control for air dampers, VAV units.

N200 Non-Spring Return Damper Actuators offers modulating control for air dampers, VAV units, air handling units, ventilation flaps, louvers, and reliable control for air damper applications with up to 20-34 Nm.

Rotary Actuators are equipped with standard On-Off or modulating control quarter-turn electric actuator also provide feedback output signal and dry contact for On-Off version

S03 series low-torque spring-return direct-coupled actuators (DCA) are used within heating, ventilating, and air-conditioning (HVAC) systems.

S05 Series Low-Torque Spring-Return Direct Coupled Actuators are used within heating, ventilating, and air-conditioning (HVAC) systems. They can drive a variety of quarter-turn, final control elements requiring spring return fail-safe operation.
