Dwyer Instruments 3HBAV0312 | Three-Way detachable electric ball valve | Cv value 7.0 | 3/4" NPT | 120 VAC | floating
The Dwyer 3HBAV0312 three-way electric ball valve is a detachable 3-way motorized valve with a 3/4" NPT connection, floating control, and a 120 VAC actuator. With a Cv of 7.0, it is designed for automated mixing and diverting of hot- and chilled-water flow in HVAC, heating, and industrial water systems.
Part No.: 3HBAV0312
The Dwyer 3HBAV0312 combines a 3-way ball valve body with a detachable electric actuator to provide automated mixing or diverting control for water circuits. It can blend hot and cold water or route flow between ports in HVAC, heating, and industrial water applications.
The actuator includes position switches and a local position indicator, along with a manual override. Its detachable design allows the actuator to be removed from the valve body for servicing without breaking the pipe connection, helping simplify maintenance.
The valve uses floating three-point control, allowing a BMS or local controller to command open, close, and stop operation. The 120 VAC actuator supply is suitable for control systems using this building and industrial control voltage.
With a Cv of 7.0, the 3HBAV0312 is sized for 3/4" NPT branch and mixing circuits where automated flow routing or blending is required rather than simple two-way shutoff.
For applications requiring a different actuator supply voltage, the Dwyer 3HBAV0314 provides the same 3/4" NPT connection and floating control with a 24 VAC actuator.

Who This Product Is Best For
The Dwyer 3HBAV0312 is suitable for HVAC and process controls contractors, building automation professionals, and system integrators who need a motorized 3-way ball valve with a 3/4" NPT connection, floating control, and 120 VAC actuator supply.
It is particularly useful for applications requiring automated mixing or diverting of hot- and chilled-water circuits.
How to Use
- Install the 3HBAV0312 at the required 3-way mixing or diverting point using the 3/4" NPT connection.
- Connect the 120 VAC actuator supply according to the installation requirements.
- Connect the floating three-point control signal to the BMS or local controller.
- Configure the controller for the required open, close, and stop operation.
- Commission the actuator and verify that the valve correctly mixes or diverts flow between the ports.
Frequently Asked Questions
