VA-4233 Series Electric Valve Actuator
Mounted on a VG7000 Series
Bronze Control Valve
VA-4233 Series Electric Valve Actuators
Code No. LIT-1900125 Issued January 2, 2014
Description
VA-4233 Series Electric Valve Actuators use a stepper motor to accurately position control valves in HVAC applications. In the event of a power failure, a spring in the actuator automatically returns the valve to the full stem-up position. These direct-mount, spring-return electric actuators provide a minimum 61 lb (271 N) force output for floating, on/off, or proportional control, and can be easily field mounted or ordered factory coupled to Johnson Controls® 1/2 through 1-1/4 in. VG7000 Series Bronze Control Valves, with no additional linkages required.
The VA-4233 Series can also be field mounted to select Barber-Colman® valves, using mounting kits available from Johnson Controls. Proportional control models include an AUTO stroke calibration feature that eliminates the need for manual calibration or adjustment after installation. Integral auxiliary switches are available to indicate end-stop position or to perform switching functions. On proportional models, position feedback is also available through a proportional DC voltage signal. All models feature a hand crank for manual positioning of the valve, independent of a power supply.
Refer to the VA-4233 Series Electric Valve Actuators Product Bulletin (LIT-977552) for important product application information.
Features
• designed for use in hot water, chilled water, and steam applications, allowing for universal application
• automatic spring return returns the valve to the full stem-up position, in the event of a power failure
• simple no-linkage mounting with AUTO stroke calibration at installation (VA-4233-GGx models only) reduces installation time and cost
• reversible stroke direction (VA-4233-GGx models only) expands usability by allowing switch-selectable direct or reverse action
• optional auxiliary switches provide adjustable switch points with line voltage capability
• 0 (2) to 10 VDC, 6 to 9 VDC, or 0 (4) to 20 mA input (VA-4233-GGx models only) provides enhanced control solutions
• optional power supply output of 20 VDC at 25 mA (VA-4233-GGx models only) provides power for external devices, making the VA-4233-GGx an ideal replacement for Barber-Colman retrofit installations
• manual hand crank allows for manual positioning of the valve, independent of a power supply
• integral position indicator provides visual indication of the valve stem position
• 1/2 in. conduit connector with 48 in. wire leads meets national and local code requirements for wiring, and allows easy field wiring on retrofit jobs
