Dwyer Instruments 3HBAV0224 | Three-Way detachable electric ball valve | Cv value 4.5 | 1/2" NPT | 24 VAC | modulating
The Dwyer 3HBAV0224 is a three-way detachable electric ball valve with 1/2" NPT connections, Cv 4.5, modulating control, and a 24 VAC actuator. Designed for mixing and diverting applications, it provides proportional flow control for hot- and chilled-water HVAC loops, heating systems, and industrial water circuits.
Part Number: 3HBAV0224
The Dwyer 3HBAV0224 combines a 3-way ball valve body with a detachable electric actuator, providing controlled mixing or diverting of flow in HVAC, heating, and industrial water systems.
The actuator supports proportional 0-10 VDC or 4-20 mA modulating control signals, allowing the valve position to be adjusted between fully open and fully closed. This makes the valve suitable for applications where precise flow positioning is required rather than simple on/off operation.
The 24 VAC actuator supply is compatible with common building automation and industrial control systems. The actuator also includes position switches, a local status indicator, and a manual override for convenient operation and commissioning.
A key advantage of the 3HBAV0224 is its detachable actuator design. The actuator can be removed from the valve body for servicing without breaking the existing pipe connection, helping simplify maintenance.
With a Cv of 4.5, the 3HBAV0224 is suited to 1/2" NPT branch, mixing, and diverting circuits where flow needs to be blended or routed between ports.
For a floating-control alternative, the Dwyer 3HBAV0214 provides the same 1/2" NPT, 24 VAC configuration with floating control.

Who This Product Is Best For
The Dwyer 3HBAV0224 is suitable for HVAC and process controls contractors, building automation professionals, and system integrators who need a motorized three-way ball valve with modulating control for mixing or diverting hot- and cold-water circuits.
It is particularly useful where proportional valve positioning is required for controlled flow management.
How to Use
- Install the 3HBAV0224 at the required three-way mixing or diverting point in the 1/2" NPT piping.
- 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 and commission the actuator's operating range through the control system.
- Verify that the valve correctly mixes or diverts flow in response to the control signal.
