Honeywell VBN2AFPA3001 Control Ball Valve NPT Cv Proportional Non-Spring Return - 2-Way 1/2 2 24V

The Honeywell VBN2AFPA3001 is a 2-way characterized control ball valve assembly with a factory-installed proportional (modulating) non-spring return actuator, designed for precise flow regulation in commercial HVAC systems. With a 1/2-inch female NPT connection and a Cv of 2, this valve delivers reliable two-position or modulating control for hot and chilled water applications with glycol solutions up to 50%.

The valve body is constructed of nickel chrome-plated brass and features Honeywell's patented seat design with reinforced PTFE (Teflon™) ball seals and EPDM O-rings, enabling tight shutoff performance. The direct-coupled MVN actuator provides 27 in-lb of torque with a 90° rotational stroke and operates on 24 VAC with a 2–10 VDC proportional control signal.

Key Features:

• 2-way, straight-through flow configuration with 1/2" female NPT connections
• Flow coefficient (Cv): 2.0 — equal percentage flow characteristic for precise modulation
• Non-spring return (fail-in-place) actuator — maintains last position on power loss
• 24 VAC power supply with 2–10 VDC proportional modulating control signal
• Nickel chrome-plated brass valve body for corrosion resistance
• Patented seat design with PTFE ball seals and EPDM O-rings for tight shutoff
• Actuator can be mounted in any of four orientations for flexible installation
• Removable manual operating handle for valve control during installation or power failure
• Body pressure rating: 360 psi maximum
• Humidity rating: 5% to 95% RH non-condensing; IP40 enclosure protection
• Design life: 60,000 cycles at rated voltage

Suitable for heating, ventilating, and air conditioning (HVAC) systems controlling hot or chilled water with up to 50% glycol solutions. Not rated for steam or fuel service. The VBN2AFPA3001 ships as a complete valve and actuator assembly, ready for direct installation.
