VA9203-BUB-2 Johnson Controls Actuator

Part number VA9203-BUB-2 from Johnson Controls, listed in IEC Contactors. KKM Solutions quotes this part with pricing and availability confirmed per order.

Overview The Johnson Controls VA9203-BUB-2 is a bidirectional electric spring-return valve actuator designed to provide on/off control for ball valves in HVAC applications. The actuator operates on a wide range of supply voltages from 85 to 264 VAC and mounts directly to the valve body without requiring a separate linkage. Features Mechanical spring return system provides reliable fail-safe operation without batteries Direct-coupled design enables quick attachment directly to the valve with a single captive screw Reversible mounting supports both clockwise and counterclockwise operation Integral, adjustable line-voltage SPDT auxiliary switch for signaling or safety interfacing Electronic stall detection protects the motor from overload across the full rotation range Double-insulated construction eliminates the need for an electrical ground connection Rugged IP54/NEMA 2 rated housing protects against dust and splashing water Specifications Actuator Type: Electric Spring Return Control Signal: On/Off (Two Position) Supply Voltage: 85 to 264 VAC at 50/60 Hz Torque: 27 lb-in (3 N-m) Fail-Safe Mode: Spring Return Rotation Stroke: 90 degrees Runtime: 75 seconds (powered); 25 seconds (spring return) Auxiliary Switch: 1 SPDT, 5.0 A at 240 VAC (continuously adjustable) Enclosure Rating: NEMA 2, IP54 Electrical Connection: 48-inch appliance cable with colored and numbered conductors Maximum Operating Temperature: 140°F (60°C) Applications The VA9203-BUB-2 is primarily used in heating, ventilating, and air conditioning (HVAC) systems to control the flow of chilled water, hot water, and low-pressure steam. It is engineered for direct-mount installation onto Johnson Controls VG1000 Series ball valves, specifically accommodating 1/2-inch, 3/4-inch, and 1-inch (DN15, DN20, and DN25) sizes. It can receive on/off control signals from manual switches, electronic controllers, or fan motor contactor auxiliary switches.
