Hattersley waterworks valves are now being stocked, distributed and marketed by Viking Johnson following the acquisition of Hattersley Newman Hender by parent company Crane Fluid Systems. The range includes eccentric and multi-port plug valves, and Flex Check, flexible disc check valves. Used for isolation, control and backflow prevention of potable and wastewater, slurries, sludges, gases and powders, they can now be supplied ex-stock from Viking Johnson in Hitchin.
