3-Way Motorized Ball Valves provide electrically actuated flow diversion and line switching in threaded piping systems where a quarter-turn ball valve is preferred for directional control. The BV Series uses a brass 3-way L-port body with electric motorized actuation for changeover, bypass, and routed flow applications.
This series comes in 1/2 inch to 1-inch female NPT sizes and pairs with the XR33 actuator, supporting applications that require 3-way directional control, compact installation, and continuous duty operation.

Pressure, Temperature, and Media Fit
The BV Series operates from 0 to 185 psi, which makes it suitable for systems that need 3-way directional control without depending on differential pressure for actuation. The listed media temperature range is 35 to 200°F.
Typical service references include process water control and flow diversion, compressed air systems, non-aggressive chemical handling, HVAC and building automation changeover systems, filtration bypass routing, and industrial water distribution line switching. However, you must still check material compatibility before your final selection if your media chemistry is more demanding.
Dimensions and Size Range
The BV Series offers compact threaded sizes from 1/2 inch to 1 inch. These sizes suit smaller changeover, bypass, and routed flow installations; however, you must verify the actuator envelope and body length before starting your installation.
| Pipe Size | Port Size D1/D2 | d (mm) | L1 (mm) | L2 (mm) | E1 (mm) | H1 (mm) | H2 (mm) |
|---|---|---|---|---|---|---|---|
| 1/2 inch | 1/2 inch | 12 | 70 | 17.5 | 27 | 72.5 | 17 |
| 3/4 inch | 3/4 inch | 15 | 75 | 17 | 31 | 76 | 20.5 |
| 1 inch | 1 inch | 18 | 85 | 17.8 | 38 | 78 | 22.5 |

Technical Note
These valves are not intended for use in medical life support, combustion, aviation, aerospace, automotive, or similar applications. Material compatibility should be reviewed before final selection, especially where media chemistry, temperature, or system duty could affect long-term seal performance.
