Johnson Controls VA-7153-1001 Actuator

The Johnson Controls VA-7153-1001 is a commercial-grade, synchronous motor-driven actuator designed for incremental control of valves in professional HVACR systems. Engineered for precision, this 24Vac valve actuator provides a robust 90 lb-in torque, ensuring positive close-off on VG7000 Series bronze valves and various flare valve bodies. Unlike standard models, the VA-7153-1001 features an integrated 2k ohm position feedback potentiometer, allowing contractors to monitor real-time stem position via the control system. The non-spring return operation is supported by a magnetic clutch that protects the gear train during stall conditions, maintaining constant output force without the risk of motor burnout.

Designed for streamlined field installation, the unit utilizes a direct coupled yoke design that accommodates a stroke range of 5/16" to 25/32". The three-wire incremental configuration with screw terminals simplifies 16 AWG wiring, while the NEMA 2 (IP42) enclosure provides necessary protection for mechanical rooms. This electric globe valve actuator is ideal for hot water and chilled water applications where reliable, long-cycle performance is required. By selecting between direct and reverse action during setup, technicians can customize the response to the 24 Vac input signal, making it a versatile choice for maintaining tight building automation setpoints.

• Precise Feedback: The 2k ohm potentiometer offers remote position indication for accurate system monitoring and diagnostics.
• High Torque Reliability: Delivers a minimum of 90 lb force to ensure secure valve seating and prevent leakage in high-demand environments.
• Motor Protection: Integrated magnetic clutch provides constant pressure while preventing mechanical failure during end-of-stroke stall.
• Universal Mounting: Features a unique yoke design compatible with Johnson Controls VG7000, VB-3766, and 4332 bronze valve bodies.
• Field Flexibility: Jumper-selectable direct and reverse action allows for quick adjustment to match specific controller logic without changing hardware.

How do I wire the VA-7153-1001 for position feedback?
The unit features internal screw terminals; use the designated feedback terminals to connect the 2k ohm potentiometer to your controller's analog input to track the 3/4-inch stroke position.

Can this actuator be used on valves with a stroke longer than 3/4 inch?
No, this model is specifically calibrated for a maximum stroke of 25/32 inch. Using it on longer-stroke valves may result in incomplete travel or mechanical stress.

What is the difference between the VA-7150 and the VA-7153?
While both provide three-wire incremental control and 90 lb-in torque, the VA-7153 includes a position feedback potentiometer, which the standard VA-7150 lacks.
