The VA9300 Series Electric Non-Spring Return Actuators are direct mount actuators for valves with ISO Flange mounting such as the VG1000 Series Valves. The series provides Automatic Signal Input Detection which allows automatic recognition of input signals for on/off, floating, and proportional control. An optional line voltage auxiliary switch kit can be field installed to indicate an end-stop position or perform switching functions within the selected rotation range. The VA9300 Actuators also feature a NEMA 4X weather shield for applications in harsh environments.
