Description
Honeywell MP918B1196 Pneumatic Damper Actuator Overview
The Honeywell MP918B1196 is a high-force, spring-return pneumatic damper actuator engineered for reliable damper control in commercial and industrial HVAC systems. With a robust 3½” stroke and a wide operating temperature range of -40°F to 158°F, this actuator performs dependably across demanding environments. Its spring-return design ensures fail-safe damper positioning upon loss of pneumatic signal, making it an essential component in building automation and air handling applications.
