The NF/AF series 120 VAC on-off actuators are functionally replaced with the NFBUP and AFBUP in all damper applications and in valve applications using the standard U-Bolt Clamp. The “UP” indicates universal power supply for 24-240VAC or 24-125VDC signal input. Actuator dimensions are smaller for the replacement actuator and may require field modification of the anti-rotation strap; or utilize provided retrofit mounting bracket Z-AF to match mounting dimensions of the original NF/AF series actuator.
When used on a characterized control valve the replacement is AFRBUP. An accessory WAF-4 linkage kit can also be used on a standard AFBUP to mount it to the CCV.
