500X relief valve

500x relief / holding pressure valve King will be used for fire or other water systems to prevent system overpressure or fire service system to maintain the pressure. After the fire pump is turned off can also reduce the impact of water hammer. Also used in large-scale water supply systems water hammer eliminating device. And inlet valve control system is equipped with a self-cleaning filter, the use of fluid properties, so that a larger proportion of larger diameter suspended particles do not enter the control system. Ensure unimpeded circulation system, the valve can be safely and reliably. Smooth system operation, high strength, long life suitable for pipe diameter 600 or less. When the water supply pressure exceeds the rated pressure relief valve, pressure relief valve opens to prevent pipeline and equipment damage due to overpressure, it can be used for high-rise building fire relief circulatory system of measurement used, causing the system to prevent the risk of excessive pressure .
