Honeywell VBN3ABPA3000 3-Way Control Ball Valve 1/2" NPT 4.3 Cv Modulating

The Honeywell VBN3ABPA3000 is a 1/2-inch three-way control ball valve designed for hot and chilled water applications in HVAC systems, including glycol solutions up to 50%. This characterized flow valve features a low-torque design with equal percentage flow characteristics that closely match industry-standard globe valve Cv ratings.

Key Features:

• 1/2-inch female NPT threaded connections for easy installation
• 4.3 Cv flow coefficient for precise flow control
• Nickel-chrome plated brass ball and stem construction
• Factory-mounted MVN modulating actuator with fail-in-place operation
• 24 VAC proportional control for accurate modulating functions
• ANSI Class IV close-off rating (maximum 0.01% of Cv leakage)
• Packless stem design that is field-serviceable without removing valve from piping
• EPDM O-rings with 600 PSI rating for reliable sealing
• Standard profile mounting bracket compatible with all Honeywell actuators

The valve installs in a "T" configuration typical for three-way mixing or diverting applications. The VBN3 series uses a patented seat design that reduces required actuator torque, allowing a 35 lb-in actuator to provide sufficient closing force at rated close-off pressure. Suitable for building automation systems requiring precise temperature control in heating and cooling applications.
