Product Description
We have been supplying the Hansen brand (made in New Zealand) Max-Flo trough and tank valve for several years to many happy clients. The Max-Flo valves are extremely reliable, have an internal diaphragm to allow massively high volumes of water through the valve and, they operate at up to to 1,200 kPa which is around 170 psi. Supplied complete with the blue float, stainless steel hardware and adaptors for 25mm, 32mm and 40mm fittings, the Max-Flo is, in my opinion, the most reliable float valve for troughs and tanks on the market today. We have sold several hundred of the Max-Flo to cattle farmers in the New England region of NSW, up on top of the Great Dividing Range where it is very cold in winter and so far we have only had 3 split diaphragms out of more than 200 valves over 5-years. Many of our clients operate their valves at pressures between 700 and 1,200 kPa so the Max-Flow valve has proven itself to be reliable, efficient and long lived.
