Pre-fill valves give you on/off control of the existing descale water for pre-filling the spray headers. This prevents the shock that occurs within the descale piping system when the main descale spray valves are opened to an empty header. The pre-fill valve is installed as a bypass around the descale spray valve. The versatility of our 2-inch and 3-inch descale spray valves make them the perfect choice for use as header pre-fill valves,
