Honeywell MP913A1177 Pneumatic Variable Volume Damper Actuator, Spring Return

Description

Honeywell MP913A1177 Pneumatic Variable Volume Damper Actuator

The Honeywell MP913A1177 is a pneumatic variable volume (VAV) damper actuator engineered for precise, reliable control of air distribution in commercial HVAC systems. Featuring a spring-return design, this actuator automatically returns to its fail-safe position upon loss of air pressure, ensuring safe and consistent system operation. Its low actuator force output makes it well-suited for lightweight damper assemblies where minimal loading is required.

Key Features

• Spring-return operation for automatic fail-safe positioning
• Low actuator force design — ideal for variable volume damper applications
• Barbed fitting sized for 1/4″ OD plastic pneumatic tubing for easy field connections
• 3–13 PSI spring range for proportional control response
• 30 PSI maximum operating pressure
• Includes a 90-degree angled mounting bracket for versatile installation orientations
• Includes 3/8″ threaded connection hardware for secure mounting
