Description
Overview
The Honeywell VBN3AHPX0000 is a 1/2″ NPT, 3-way brass ball valve engineered for precision flow control in commercial chilled and hot water HVAC systems. With a Cv of 4.30, this valve delivers reliable, repeatable performance across a wide range of hydronic heating and cooling applications. Its robust brass body paired with a nickel-chrome plated brass ball and stem ensures long-term durability and corrosion resistance in demanding environments.
Flow Characteristics
- Equal Percentage flow characteristic on Port A to AB — ideal for modulating control and stable loop performance
- Linear flow characteristic on Port B to AB — provides proportional response for mixing or diverting applications
- 3-way configuration supports both mixing and diverting service
