This product is a nickel-plated brass lever valve that is installed in-line with a pipe and comes with two brass hose barbs in various sizes. Its purpose is to regulate the flow of water in the connected pipe or to turn the water on and off. The valve is designed to allow for full flow, meaning that it does not interrupt the water flow, resulting in a consistent water output. The lever on this valve is made of metal and can be easily operated with a quarter turn from fully on to fully off. It requires less strength to operate than traditional turn handles. The brass hose barbs are designed to fit securely into the pipe and are resistant to snapping, even under pressure. This product is perfect for use in garden irrigation systems, ponds, and fountains.
