  • Summary
  • Applications

    Plumbing and HVAC

  • Description

    The Armstrong Circuit Balancing Valves (CBV) provide precision flow measurement, pump throttling and temperature measurement capabilities. ½” to 2” models feature multi-turn adjustment for precise control, hidden memory stops to set balance point and soft seats for positive shutoff.

  • Materials


  • Configuration

    Compact Mini Sweat CBV-MS is available in ½” and ¾” sizes with solder-type connections

  • Temperature

    -20°C to 150°C (-4°F to 300°F)

  • Size

    15 mm – 50 mm (½” to 2”)

Easy setup and high accuracy

  • High precision, fixed orifice PMD assures faster setting and superior accuracy
  • Integral fixed KV primary measuring element for maximum differential pressure signal stability and optimum flow correlation accuracy (measured vs. actual flow rate accuracy of ±5% across 95%, or higher, of the operating range)

Design Envelope

Lowest installed cost. Lowest operating cost.


Superior flow control

  • Five full 360° turns from open to closed, providing unparalleled flow control and energy savings
  • Micrometer-style handle enables precise flow-rate adjustment
  • Line size optimization for ideal performance for 0.7 to 1.3 m/s flow velocity
  • Wye pattern, globe-style valve design for reduced turbulence
