Dwyer Instruments 3HBAV0212 | Three-Way detachable electric ball valve | Cv value 4.5 | 1/2" NPT | 120 VAC | floating
The Dwyer 3HBAV0212 is a three-way detachable electric ball valve with 1/2" NPT connections, Cv 4.5, floating control, and a 120 VAC actuator. It is designed for mixing and diverting applications in hot- and chilled-water HVAC loops, heating systems, and industrial water circuits.
Part Number: 3HBAV0212
The Dwyer 3HBAV0212 combines a 3-way ball valve body in 1/2" NPT with a detachable electric actuator, providing automated mixing and diverting control for hot and cold water circuits.
The actuator uses floating three-point control, allowing open, close, and stop commands from a BMS or compatible controller. This makes the valve suitable for applications where flow needs to be routed or blended between ports rather than simply controlled as an on/off shutoff valve.
The 120 VAC actuator supply is suitable for building and industrial control systems where this voltage is available. The actuator includes position switches and a local status indicator, along with a manual override for convenient operation during commissioning or service.
The detachable actuator can be removed from the valve body for servicing without breaking the pipe connection, helping simplify maintenance and reduce disruption to the installed piping.
With a rated Cv of 4.5, the 3HBAV0212 is sized for 1/2" NPT branch and mixing circuits where a single valve is required to blend or divert flow between ports.
The 3HBAV0212 is part of Dwyer Instruments' three-way electric ball valve range. For assistance confirming the correct variant for your application, contact GeneralTech Shop.
