ARMSTRONG AIR® 571110-351 1076785

ARMSTRONG AIR® Circuit Balancing Valve, 3/4 in Nominal, Sweat, 7 gpm

• The Armstrong circuit balancing valves (CBV) Provide precision flow measurement, pump throttling and temperature measurement capabilities, 1/2 to 2 in models feature multi-turn adjustment for precise control, hidden memory stops to set balance point and soft seats for positive shut-off
• 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)
• Five-full 360 deg 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/sec flow velocity
• Wye pattern, globe-style valve design for reduced turbulence
• Soft seats for positive shut-off
• Hidden memory stop saves setting after shut-off/servicing and prevents accidental setpoint tampering
