Description
Honeywell VBN3CJPX6400 — 3-Way Ball Valve Assembly Overview
The Honeywell VBN3CJPX6400 is a fully assembled 3-way spring-return ball valve designed for precise flow control in commercial HVAC hydronic systems. Featuring a brass body with plated brass trim, this valve delivers reliable, long-service performance in demanding heating and cooling applications. The normally open (B-AB) configuration ensures fail-safe operation, while the integrated actuator supports multiple control signal inputs for maximum compatibility with modern building automation systems.
Key Features
- 3-way, B-AB normally open (N.O.) spring-return ball valve assembly
- 1″ NPT connection for straightforward installation
- Flow coefficient (Cv): 8.60 — suitable for a wide range of hydronic applications
- Equal percentage flow characteristic: Port A to AB
- Linear flow characteristic: Port B to AB
- Brass body with plated brass trim for corrosion resistance and durability
- Spring-return actuator provides fail-safe positioning on power loss
Electrical & Control Specifications
- Supply voltage: 24 Vac
- Control signal inputs: 0–10 Vdc and 2–10 Vdc (floating/proportional)
- Current input: 4–20 mA with integrated 500-ohm resistor
- Multi-signal compatibility simplifies integration with DDC and BAS controllers
Application & Benefits
- Ideal for fan coil units, air handling units, and hydronic heating/cooling coils
- Normally open design maintains flow during power interruption for system protection
- Equal percentage and linear flow characteristics allow accurate zone-level control
- Compact, pre-assembled design reduces installation time and labor costs
- Compatible with Honeywell and third-party building automation systems
