Honeywell VBN3ABPA0000 3-Way Threaded Control Ball Valve 1/2 Inch 0.59 CV

The Honeywell VBN3ABPA0000 is a 1/2-inch, 3-way threaded control ball valve designed for hot and chilled water control in HVAC systems. This valve-only model features a CV rating of 0.59 and a close-off pressure rating of 50 PSI, making it ideal for modulating flow control in hydronic heating and cooling applications.

Key Features:

• Female NPT threaded connections for easy installation
• Characterized equal percentage flow for precise control
• Nickel-chrome plated brass construction for durability
• Low-torque design requiring only 35 lb-in actuator
• Pack-less valve stem assembly that is field-replaceable
• EPDM O-rings with 600 PSI minimum rating
• ANSI Class IV leakage rating (0.01% of CV maximum)
• Universal mounting bracket compatible with all Honeywell actuators

The VBN3 Series features a patented seat design that significantly reduces the torque needed from the actuator while maintaining reliable close-off performance. The valve body can be configured for T-configuration installations typical of 3-way mixing or diverting applications. This valve requires a separate Honeywell actuator (sold separately) with 44 in-lb torque capacity for proper operation. Not suitable for use with steam or fuel applications.
