Resideo Braukmann ms7505a2030 Fail-safe Spring Return Actuator Ball Butterfly Globe Valve Damper 44 In-lb 24V Ac

Product Description

The Resideo Braukmann MS7505A2030 is a fail-safe spring return actuator designed for use with ball valves, butterfly valves, cage valves, dampers, and globe valves in building automation and HVAC control systems. This actuator uses a 24V AC power supply and delivers a rated torque of 44 in-lb, making it well suited for a wide range of commercial and industrial valve and damper applications. The MS7505A2030 supports both floating point and proportional control signals, giving building automation engineers and HVAC technicians the flexibility to integrate it into a variety of control strategies. Proportional control allows the actuator to position the connected device anywhere along its stroke, while floating point control drives the actuator open or closed in response to a signal from the controller. A 0 to 10V DC output signal provides feedback to the building management system for precise monitoring and diagnostics. The spring return mechanism is the defining safety feature of this actuator. In the event of a power loss or emergency, the internal spring automatically returns the connected valve or damper to a predetermined safe position. This makes the MS7505A2030 an essential component for critical infrastructure where valves and dampers must move to a safe state without relying on external power. The actuator features direct mount installation with a self-centering clamping shaft adapter and includes a mounting bracket, simplifying field installation for mechanical contractors and HVAC technicians. Shaft rotation is selectable for both clockwise and counterclockwise operation, with a stroke angle of 95 degrees. The unit is rated NEMA 2 and IP54 for protection against dust and water ingress, making it suitable for mechanical rooms and light industrial environments. Electrical connections are made via screw terminals. Power consumption is 7.5 VA, and the time to close is 90 seconds. Operating temperatures range from -22 F to 149 F. The overall dimensions are 7.5 inches in height, 3.625 inches in width, and 3.125 inches in depth. This actuator is compatible with building automation systems and is manufactured in Mexico.
