Honeywell VBN2 Two-way Threaded Control Ball Valve

Two-way Threaded Control Ball Valve

The VBN2 Two-Way Control Ball Valves control hot and chilled water with glycol solutions up to 50% in heating, ventilating, and air conditioning (HVAC) systems to provide two-position or modulating functions. These valve assemblies can be ordered with or without factory-mounted non-spring return or spring return direct-coupled actuators (DCA).

• Sizes from 1/2 inch to 2-1/2 inches with internal (female) NPT connections
• Equal percentage or linear flow characteristics
• Choice of four, factory-installed actuation control schemes: Floating, Modulating (2-10 V), Spring Return 2-Position, Spring Return Modulating/Floating
• Field configurable for normally open or normally closed fail-safe position
• Removable manual operating handle to control valve during installation or in an event of power failure
• ANSI Class IV seat leakage specification (0.01% of CV)
• Optional NEMA 3R (IP54) rated enclosure for outdoor applications
• Actuator can be mounted on the valve in any of four positions
• Sizes up to 3 inches
• Wide CV choices from 0.38 to 266
• Nickel-chrome plated brass or 316 stainless steel valve ball and stem
