Johnson Controls VA-7482-2001 Actuator
The Johnson Controls VA-7482-2001 is a compact, motorized linear electric actuator engineered for proportional control of terminal unit valves and pressure-independent control valves (PICVs).
The VA-748x Series Electric Terminal Unit Valve Actuator provides floating, proportional, or proportional control with 0-10V position feedback signal and electric fail safe function in HVAC applications. The compact design of this actuator series makes it suitable for installation in confined locations, such as fan coils, chilled ceilings, manifolds, and more.
The VA-748x Series Actuator is designed for field mounting onto Johnson Controls and competitors’ terminal unit valves. Due to the innovative concept of auto stroke detection, the VA-748x can be installed over most of the conventional terminal unit valves and pressure independent control valves (PICV) with variable strokes on the market.
VA-748x Series Features:
-
Low and line voltage — Flexible applications
- Floating and proportional control — Flexible applications
-
Voltage and current analog input — Suitable for any controller
- Different analog input ranges — Flexible applications
- Different actuator speeds — New market opportunities
- Double and RGB colour LED — Provide information about status and diagnostic
- Removable cable — No expert required for connection or replacement
- Different cable length available as separate kit — OEM’s version easily available
- Auto stroke detection — Suitable for valve with variable stroke
- Feedback control — 0-10 VDC with max. 2mA output current
- Electrical fail safe — Protects the equipment and the system from damage, while enhancing overall efficiency

Johnson Controls VA-7482-8201 Valve Actuator for Proportional Control
The Johnson Controls VA-7482-8201 is a compact linear electric valve actuator designed for proportional (modulating) control in HVAC applications like fan coil units and chilled ceilings.
It features a "Reverse Acting" (RA) configuration and uses an innovative auto-stroke detection system to calibrate itself to various valve types automatically.
Technical Specifications
- Control Type: Proportional with a 0–10 VDC signal and position feedback.
- Actuator Force: Provides a linear force of 160 N.
- Power Supply: Operates on 24 VAC/VDC.
- Speed/Timing: Features an 8-second full-stroke operating time.
- Protection: Rated IP54 for high resistance to dust and splashing water.
- Connection: Uses a standard M30 x 1.5 threaded coupling for field mounting.
- Cable: Typically includes a 2-meter, halogen-free pre-installed cable.
Key Features
- Auto Stroke Detection: This feature allows the actuator to adjust automatically to the variable strokes of terminal unit valves and pressure-independent control valves (PICV).
- Reverse Acting (RA): Specifically configured to act in reverse of the standard control signal (typically extending the stem as the signal decreases).
- Status Indicators: Proportional models like this one are equipped with a bi-color green/red LED to provide real-time operating status and diagnostic information.
- DIP Switches: Includes six internal DIP switches that allow users to configure specific operating parameters in the field.
