Honeywell MP909E1158 Spring Return Damper Actuator 913 PSI

The Honeywell MP909E1158 is a spring return damper actuator designed for reliable HVAC control applications. This pneumatic actuator features a 913 PSI operating pressure range and comes equipped with a 3/8-16 threaded shaft for secure mounting to damper assemblies.

Key Features:

• Spring return operation ensures fail-safe positioning during power loss
• 913 PSI pressure range for consistent torque output
• 3/8-16 threaded shaft compatible with standard damper linkages
• Durable construction for commercial and industrial HVAC systems
• Direct mounting design simplifies installation

This actuator is ideal for controlling air dampers in heating, ventilation, and air conditioning systems where automatic return to a safe position is required. The spring return mechanism provides reliable fail-safe operation, returning the damper to its default position when air pressure is removed.
