JOHNSON CONTROL VA9208-AGA-1

Applications The VA9208-AGx-x Series On/Off and Floating Point Electric Spring Return Actuators are direct-mount valve actuators that operate on AC/DC 24 V power. These bidirectional actuators are used to provide accurate positioning on Johnson Controls® VG1000 Series 1-1/4, 1-1/2, and 2 in. (DN32, DN40, and DN50) ball valves in Heating, Ventilating, and Air Conditioning (HVAC) applications. Integral line voltage auxiliary switches, available only on the VA9208-xxC-3 models, indicate end-stop position, or perform switching functions within the selected rotation range. VA9208-AGA-2 actuators include plenum-rated cables and are specially configured for installation in spaces used for environmental air-handling purposes other than ducts and plenums as specified in National Fire Protection Association (NFPA) 70: National Electrical Code section 300.22(C), Other Space Used for Environmental Air. The space over a hung ceiling used for environmental air handling purposes is an example of the type of space for which these actuators are configured.
