VBN2, VBN3 Control Ball Valves

With Threaded Connections

APPLICATION

The VBN2 Two-Way and the VBN3 Three-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).

FEATURES

All Models

• Sizes from 1/2 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 C

• Optional NEMA 3R (IP54) rated enclosure for outdoor

applications.

• Actuator can be mounted on the valve in any of four

positions.

VBN2 (Two-way)

• Sizes up to 3 inches.

•Wide C

choices from 0.38 to 266.

• Nickel-chrome plated brass or 316 stainless steel valve

ball and stem.

VBN3 (Three-way)

•Wide C

choices from 0.33 to 109.

• Valve installs in a globe valve “T” pattern, no extra

elbows or piping required.

• Nickel-chrome plated brass valve ball and stem.

• Mixing or Diverting control.

VBN2, VBN3 CONTROL BALL VALVES WITH THREADED CONNECTIONS Effective CV When valves are mounted between pipe reducers, there is a decrease in actual valve capacity because the reducers create additional pressure losses in the system. This is especially true for ball valves because of their high capacity. Table 5.

VBN2, VBN3 CONTROL BALL VALVES WITH THREADED CONNECTIONS Required Torque 1. Both Honeywell non-spring return and spring return low torque direct coupled actuators can be utilized with the VBN2 and VBN3 valves. VB valves use a patented seat design that reduces the torque needed from the actuator. A 35 lb-in. DCA provides sufficient torque to close the valve at rated close-off. (See Table 6.) These ratings exceed most HVAC application requirements. Table 7. Close-off, Differential Pressure Ratings.
