Hansen Max-Flo 25/20 Short Trough & Tank Valve
Hansen Maxflo 25/20 High Flow Trough & Tank Valve
The Hansen Maxflo 25/20 is a high-performance diaphragm valve designed for rapid filling of water troughs and storage tanks. Its compact design delivers high flow rates while operating across a wide pressure range, making it suitable for agricultural, livestock, irrigation and general water storage applications.
The Maxflo incorporates Hansen’s self-cleaning pilot system, helping the valve operate reliably with both clean and dirty water. Its slow opening and closing diaphragm action also helps minimise valve bounce and water hammer, reducing unnecessary stress on pumps and pipework.
