Greenfield Direct makes motorized valves for your home's plumbing. Hook one of these valves up to your water or gas line, and then connect it to your home automation system. If there's a leak in the line, your Greenfield Direct valve will automatically close to prevent damage. It's a wonderfully effective way to keep your property in shape even when an emergency occurs. Greenfield Direct motorized valves are inexpensive exclusively at DHA.
