Caleffi has introduced the TwistFlow Distribution Manifold, which updates the company's 668 series with built-in sight-flow gauges.
These new sight-flow gages are integrated with adjustable balancing valves, allowing accurate flow rate adjustment to each circuit by simply reading the flow rate on the integral graduated scale. This simplifies and speeds up circuit calibration without cumbersome reference graphs, according to Caleffi.
Standard models are available in three to 13 circuit configurations, with 1-inch or 1.25-inch NPT inlet ball valves, a 150 psi maximum working pressure and a 180 degrees F maximum working temperature.
