The QAV uses a unique, patent-pending valve design includes a single-piece ball, stem, and handle assembly to reduce the time to assemble while strengthening the structure. The QAV Valve replaces the 35 Shut-Off, keeping only its price-point. The QAV offers greater durability and a larger handle for easier watering.
