Part No. 3HBAV0512
The Dwyer 3HBAV0512 combines a three-way ball valve body in 1-1/4" NPT with a detachable electric actuator for automated mixing and diverting of hot- and chilled-water circuits. It is suited to HVAC, heating and industrial water systems where flow needs to be blended or routed between ports rather than simply switched on or off.
The actuator includes position switches and a local position indicator for status checking, while its detachable design allows servicing without breaking the pipe connection. A manual override provides additional convenience during setup or service.
The 3HBAV0512 uses floating three-point control, allowing a BMS or controller with open/close/stop outputs to drive the actuator in the required direction. Its 120 VAC actuator supply suits compatible building and industrial control panels.
With a rated flow coefficient of Cv 17.9, this valve is sized for 1-1/4" NPT branch and mixing circuits requiring automated three-way flow control.

- Commission the actuator and verify the required valve travel and control response.
- Test the system to confirm that the valve correctly mixes or diverts flow between the required ports.
Frequently Asked Questions
What does a 3-way valve like the 3HBAV0512 do?
The 3HBAV0512 mixes or diverts flow between ports within a single valve body. This makes it suitable for applications such as blending hot and cold water or routing flow through a bypass.
What control signal does the 3HBAV0512 use?
The valve uses floating three-point control, providing open, close and stop operation from a compatible controller.
What supply voltage does the 3HBAV0512 require?
The actuator requires a 120 VAC supply.
What is the Cv of the 3HBAV0512?
The 3HBAV0512 has a rated flow coefficient of Cv 17.9.
What NPT size is the 3HBAV0512?
The valve has a 1-1/4" NPT connection size.
Can the actuator be removed for servicing?
Yes. The 3HBAV0512 features a detachable actuator that can be removed for servicing without breaking the pipe connection. It also includes a manual override.
Is the 3HBAV0512 suitable for BMS control?
Yes. Its floating three-point control can be connected to a compatible BMS or controller providing open/close/stop outputs.
What is the difference between the 3HBAV0512 and 3HBAV0514?
Both models are three-way, 1-1/4" NPT valves with floating control and a detachable actuator. The key difference is the actuator supply voltage: the 3HBAV0512 uses 120 VAC, while the 3HBAV0514 uses 24 VAC.
