Siemens Building Technology GLB146.1P Actuator 318518-761 Technicians should verify the manifoldThe Siemens GLB146. 1P Actuator is a robust, non spring return (NSR) damper actuator engineered for high performance air flow regulation in constant or variable air volume (VAV) systems. Delivering 88 lb in torque (10 Nm), this direct coupled unit is designed to handle damper areas up to approximately 16 square feet with precision. This model features 2 position and floating control logic, operating on a standard 24V AC DC power supply, making it a
