This valve is similar to the previously described LV9901 model but uses a 316 stainless steel disc instead of nickel-plated ductile iron. This offers increased corrosion resistance and potentially higher strength compared to the LV9901. However, it is important to note that only sizes 2 to 12 inches have WRAS approval, meaning they are not suitable for drinking water applications in larger sizes.
