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.

• 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)

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

Secure handling

• Soft seats for positive shutoff
• Hidden memory stop saves setting after shut-off / servicing and prevents accidental set point tampering
