The M9109 Series direct-mount electric actuators operate on 24 VAC power and are available for use with floating or proportional controllers. These non-spring return actuators are easily installed on a Variable Air Volume (VAV) box and a damper with a steel shaft up to 1/2 in. (13 mm) in diameter or 3/8 in. (10 mm) square. They may be field mounted to a VG1000 Series ball valve using the M900-512 Valve Linkage Kit. The M9109 models have an 80 lbin (9 Nm) running torque. They have a nominal 60-second travel time for 90° of rotation at 60 Hz (72 seconds at 50 Hz) with a load-independent rotation time. The M9109-xGC-2 models are available with integral auxiliary switches to perform switching functions at any angle within the selected rotation range. Position feedback is available through a 0 (2) to 10 VDC signal on the M9109-GGx-2 models.
