A. Most of the ball valves that we stock/ship are gray colored but many times we will ship them in white (especially the smaller sizes). In terms of quality they are all identical and color is no reflection of quality or ease of use or installation. If you specifically need either gray or white please do specify that in the comments area when ordering. Unless you specify we will ship whatever color is mostly in stock at the time of your order and if you order a week later for more PVC valves they might be shipped in another color. If you need a particular color, include your request in the "comments" section of your order and we will let you know if that is possible before we ship your order.
