Description
Honeywell MP909H1368 Pneumatic Damper Actuator Overview
The Honeywell MP909H1368 is a reliable pneumatic damper actuator engineered for precise damper positioning in commercial HVAC and building automation systems. Featuring a medium actuator force rating and a positive positioner with a 10 PSI span, this actuator delivers consistent, repeatable control across a wide range of air-handling and ventilation applications. Its spring return design ensures fail-safe damper positioning in the event of air supply loss, providing an added layer of system protection.
Key Features
- Medium actuator force for reliable damper positioning in commercial HVAC systems
- 10 PSI span on positive positioner for accurate and stable control response
- 4″ stroke accommodates a broad range of damper linkage configurations
- Spring return mechanism provides fail-safe operation upon loss of pneumatic supply
- 25 PSI maximum operating pressure for compatibility with standard pneumatic control systems
- 6.6 square inch diaphragm for consistent force output across the full stroke range
- Dual barbed fitting accepts both 5/32″ and 1/4″ OD tubing for flexible field installation

Application
The MP909H1368 is ideally suited for use in commercial building automation and HVAC zoning systems where pneumatic control is required. It is commonly applied to modulating outside air, return air, and exhaust dampers in air handling units, VAV systems, and economizer assemblies. The dual barbed tubing fitting simplifies field connections, while the spring return function ensures dampers default to a safe position during system shutdowns or pneumatic supply failures.
