Available in 1/2-in. and 3/4-in. models that can handle flowrates as low as 0.26 gal/min and 0.4 gal/min, respectively, these new ARMflow venturi-style balancing valves are significantly more accurate than conventional balancing valves. They require five full 360-deg. turns from open to closed, and their non-rising handle ensures that overall valve height remains the same from fully open to completely closed. They can be installed with the measuring ports facing up or down.
