Part Number: HBAV0424
The Dwyer HBAV0424 combines a stainless steel or brass ball valve body with an electric actuator, providing automated valve operation directly from a building management system (BMS), HVAC controller, or local control system.
The valve accepts a proportional 0–10 VDC or 4–20 mA modulating control signal, allowing the actuator to position the ball anywhere between fully open and fully closed. This provides more precise flow control than simple open/close operation and makes the HBAV0424 suitable for HVAC and process loops where flow needs to be adjusted according to system demand.
Its 24 VAC actuator supply is compatible with common building automation and industrial control systems, helping simplify integration where 24 VAC power is already available.
The 2-way, full-bore ball valve design helps maintain low pressure drop when the valve is open. This allows automated motorized operation while retaining the flow characteristics associated with Dwyer's manual ball valve range.
The HBAV0424 can also serve as a practical retrofit for an existing manually operated shutoff point. It enables remote, automated, or scheduled valve operation through a compatible BMS or controller, making it suitable for both retrofit projects and new HVAC or process control installations.
For applications requiring floating control rather than proportional modulating control, the Dwyer range also includes the HBAV0414, a 1" NPT electric ball valve with floating control and 24 VAC supply.

Who This Product Is Best For
The Dwyer HBAV0424 is suited for HVAC contractors, building automation professionals, and process control engineers who require a motorized 2-way ball valve with proportional modulating control in a 1" NPT system.
It is particularly useful for applications where the valve position needs to be adjusted continuously in response to system demand, including BMS-controlled HVAC flow management and automated process control loops.
How to Use
- Install the HBAV0424 in the HVAC or process line using the 1" NPT connection.
- Connect the 24 VAC actuator supply according to the installation requirements.
- Connect the 0–10 VDC or 4–20 mA modulating control signal to the BMS or compatible controller.
- Configure the controller for the required operating range and valve positioning.
- Verify that the valve opens, closes, and modulates correctly in response to the control signal before normal operation.
Frequently Asked Questions
What control signal does the HBAV0424 use?
The HBAV0424 uses modulating proportional control, supporting 0–10 VDC or 4–20 mA control signals.
What supply voltage does the HBAV0424 require?
The actuator requires a 24 VAC supply.
What is the NPT size of the HBAV0424?
The valve has a 1" NPT connection.
Is the HBAV0424 a full-bore valve?
Yes. The HBAV0424 is a 2-way, full-bore ball valve designed to maintain low pressure drop when open.
Can the HBAV0424 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" NPT piping.
Can the HBAV0424 be controlled through a BMS?
Yes. Its modulating control configuration allows operation from a compatible BMS, HVAC controller, or local control system using a proportional control signal.
What is the difference between the HBAV0424 and HBAV0414?
Both models use a 1" NPT connection and 24 VAC supply, but they use different control types. The HBAV0424 uses modulating control, while the HBAV0414 uses floating control.
