M/VA9320, M/VA9335 Series Electric NonSpring Return Actuators The M/VA9320, M/VA9335 Series Electric Non-Spring Return Actuators provide control of dampers in HVAC also control of valves with ISO Flange mounting such as VG1000 valve. All actuators in this series provide 20Nm and 35Nm torque. 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 M9320/M9335 are configured for direct mounting and do not require damper linkage. Actuators can be mounted directly to a damper shaft from 3/4 to 1-1/16 in. (19 to 27 mm) diameter and 5/8 to 3/4 in. (16 to 19 mm) square with a universal clamp. An accessory crank arm and remote mounting kit are available for applications where the actuator cannot be direct-coupled to the damper shaft. VA9320/35 can be directly installed on JCI VG1000 ball valve and VF6000 butterfly valve, and the universal linkage brings more flexibility.
