TacoSetter Bypass 3/4" Visual Calibration Valve (2-8 GPM)

The Taco Comfort Solutions TacoSetter Bypass (2-8 GPM) is the premium mechanical standard for precision hydronic loop balancing. Fabricated from solid, dezincification-resistant brass with a 3/4" female NPT interface, this inline calibration valve features an integrated bypass flow meter assembly. By compressing the manual spring-loaded bypass lever, a localized sample stream is diverted through an isolated glass sight chamber, providing instant, highly accurate visual flow-velocity readings without introducing structural system pressure drops during normal operation.

Key Mechanical & Field Advantages:

• Direct Visual Flow Reading: Eliminates the need for expensive external pressure-differential computers, calculation charts, or diagnostic probes. The internal red indicator float yields real-time GPM tracking inside the scale window.
• Isolate-Protected Measuring Element: Because the visual sight cylinder is contained within a normally closed bypass channel, it remains clean and free of system black iron oxide sediment or scaling during normal run times.
• Precision Multiturn Adjustment: Equipped with a finely calibrated, internal sloped plug mechanism that allows microscopic balancing adjustments across its entire 2.0 to 8.0 GPM operational field.

Application Dynamics: Perfect for solar thermal loop configuration, radiant floor manifolds, cooling headers, and institutional domestic hot water recirculation lines. Rated for continuous duty in water and glycol media mixtures.
