Overview

VBN3 Three-Way Control Ball Valves control hot/chilled water with glycol solutions up to 50% in heating, ventilating, and air conditioning (HVAC) systems to provide two-position or modulating functions. Ordered with/without factory-mounted actuators.

Features

  • Sizes from 1/2 to 2-1/2 inches with internal (female) NPT connections.
  • Equal percentage or linear flow characteristics.
  • Reduced B-port Cv for constant loop flow.
  • 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.
  • Wide Cv choices from 0.33 to 109.
  • Valve installs in a globe valve "T" pattern, no extra elbows or piping required.
  • Field-serviceable stem assembly.
  • Nickel-chrome plated brass ball and stem.
  • Mixing or Diverting control.
