Part Number: HBAV0512
The Dwyer HBAV0512 combines a stainless steel or brass ball valve body with an electric actuator, replacing manual valve operation with automated control from a building management system (BMS), HVAC controller, or local control system.
The valve accepts floating three-point control, allowing the actuator to drive the valve open or closed through simple open/close/stop control signals. This provides practical automated operation without requiring a more complex proportional control system.
Its 120 VAC actuator supply is suited to control panels and building or industrial systems that use 120 VAC power, helping simplify installation where compatible power is already available.
The 2-way, full-bore ball valve design maintains low pressure drop when the valve is open. This makes the HBAV0512 suitable for applications where automated control is required without unnecessarily restricting flow capacity.
The valve can also be used as a practical retrofit for an existing manually operated shutoff point. By replacing manual operation with an electric actuator, operators can control the valve remotely, automatically, or according to scheduled sequences from a BMS or controller.
For applications requiring a different actuator supply voltage, the Dwyer range also includes the HBAV0514, a 1-1/4" NPT electric ball valve with floating control and 24 VAC supply.

Who This Product Is Best For
The Dwyer HBAV0512 is suited for HVAC contractors, building automation professionals, and process control engineers who need a motorized 2-way ball valve with floating control in a 1-1/4" NPT system.
It is particularly useful for BMS-driven valve operation, automated shutoff applications, remote control, scheduled operation, and retrofit projects where an existing manual valve needs to be motorized.
How to Use
- Install the HBAV0512 in the HVAC or process line using the 1-1/4" NPT connection.
- Connect the 120 VAC actuator supply according to the installation requirements.
- Connect the floating control signals to the BMS or local controller.
- Configure the controller for the required open, close, and stop operation.
- Verify that the valve responds correctly to the control signal before placing the system into normal operation.
Frequently Asked Questions
What control signal does the HBAV0512 use?
The HBAV0512 uses floating control, also known as three-point open/close/stop control.
What supply voltage does the HBAV0512 require?
The actuator requires a 120 VAC supply.
What is the NPT size of the HBAV0512?
The valve has a 1-1/4" NPT connection.
Is the HBAV0512 a full-bore valve?
Yes. The HBAV0512 is a 2-way, full-bore ball valve designed to maintain low pressure drop when open.
Can the HBAV0512 replace an existing manual ball valve?
It can be used as a retrofit solution for automating an existing manually operated shutoff point in compatible 1-1/4" NPT piping.
Can the HBAV0512 be controlled through a BMS?
Yes. Its floating control configuration allows operation from a compatible BMS, HVAC controller, or local control system.
Should I choose the HBAV0512 or HBAV0514?
Both models use a 1-1/4" NPT connection and floating control, but they differ in actuator supply voltage. The HBAV0512 uses 120 VAC, while the HBAV0514 uses 24 VAC. Select the model that matches the available control-panel power for your application.
