Caravan pressure limiting valves with inbuilt check valves are essential components used to regulate water pressure and prevent backflow in caravan and RV plumbing systems. Designed to maintain a safe and consistent pressure—typically 350kPa—they protect hot water systems and other fixtures from damage caused by high water pressure. These valves feature standard 1/2" BSP female threads and are made from durable DR brass, ensuring long-lasting performance. Available in both 95mm and 112mm lengths, they are compatible with a wide range of caravans, including older and newer Jayco models, and meet Australian Watermark certification standards for quality and safety.
