Its compact size allows for easy installation and use in crowded piping compartments. The ball type design, extended throttling range and large indicator plate make for highly accurate flow measurement, even in very low flow ranges. The positive memory feature is easy to see, access and operate facilitating system balancing and flow measurement. This valve is also bi-directional, so there is no chance of installing the valve in the incorrect flow direction.
