Honeywell VBN3AEPX0000 3-Way Threaded Control Ball Valve 1/2" Cv 1.0 Valve Body Only

The Honeywell VBN3AEPX0000 is a 3-way threaded control ball valve body designed for precise flow control of hot and chilled water in commercial and industrial HVAC systems. With a 1/2-inch pipe size, a Cv rating of 1.0, female NPT connections, and a nickel-chrome plated brass ball and stem, this valve body ships without an actuator, allowing installers to pair it with the appropriate Honeywell MVN, MN, or MS series actuator for their specific application.

Engineered for both mixing and diverting service, the VBN3 series delivers reliable two-position or modulating flow control in heating, ventilating, and air conditioning systems. The valve accepts glycol solutions up to 50% concentration, making it well-suited for freeze-protection applications.

Key Features:

• Configuration: 3-way ball valve body, actuator sold separately
• Pipe Size: 1/2 inch with internal female NPT connections
• Cv Rating: 1.0 (equal percentage flow characteristic on Port A to AB; linear on Port B to AB)
• Body Material: Nickel-chrome plated brass ball and stem, forged brass body (ASTM B283)
• Stem Seals: Teflon™ thrust bearings with EPDM O-rings
• Ball Seals: Patented reinforced Teflon™ seals with EPDM backing
• Leakage Rating: ANSI Class IV (0.01% of Cv) on A port; ANSI Class III (0.1% of Cv) on B port
• Body Pressure Rating: 360 psi (2,482 kPa) maximum
• Close-off Pressure: 50 psid minimum (actuator dependent)
• Controlled Media: Water or glycol solutions up to 50%; not for use with steam or fuels
• Profile: Standard profile — provides clearance between valve body and actuator for insulation
• Service: Mixing or diverting control; installs in a T-configuration without requiring elbows
• Patented Seat Design: Reduces actuator torque requirement for reliable shutoff

The VBN3AEPX0000 is compatible with Honeywell's full line of spring-return and non-spring-return MVN, MN, and MS direct-coupled actuators. Actuators can be configured for floating, modulating (2–10 Vdc), or two-position control and are field-configurable for normally open or normally closed fail-safe positions. A removable manual operating handle is supported for use during installation or in the event of a power interruption.
