Armstrong Pumps, a supplier of fluid flow equipment for residential, commercial and industrial applications, has introduced its ½” to 2” circuit balancing valves (CBVs). These are designed to meet the needs of engineers, installing contractors, balancing contractors, and building owners alike. The patent-pending design of Armstrong’s venturi-style balancing valves produces significantly higher balancing accuracy than that with conventional balancing valves. In addition, Armstrong ½” to 2” balancing valves have five full 360° turns from open to closed, providing unparalleled flow control. Featuring a compact and versatile design, the Armstrong ½” to 2” balancing valves can be installed with the measuring ports facing up or down. The non-rising handle of these new CBVs ensures that the overall valve height remains the same from fully open to completely closed.
