Description
The Honeywell VBN3AEPA0000 is a 3-way brass ball valve engineered for precise flow control in chilled and hot water HVAC hydronic systems. Featuring a 1/2″ NPT connection and a 1.00 Cv flow coefficient, this valve delivers reliable, repeatable performance in commercial and light industrial applications.
The VBN3AEPA0000 uses an equal percentage flow characteristic on Port A to AB for fine throttling control at low flow rates, while Port B to AB provides a linear flow characteristic for proportional, predictable response. This dual-characteristic design makes it ideal for mixing or diverting applications where precise system balance is critical.
Constructed with a durable brass body and a nickel-chrome plated brass ball and stem, this valve resists corrosion and wear for long service life. The standard base mount allows for easy pairing with compatible Honeywell actuators, enabling automated control in building automation and HVAC zoning systems.
