Vortex trough valves are float operated valves for use in automatic filling of water troughs, tanks, cisterns etc. The valve is configured for above or below water mounting. The float operates a small pilot valve which in turn operates the main diaphragm valve. Vortex trough valves are a good choice where their high flow, compact, robust, non corrosive construction and high level of adaptability are needed. Applications: Maintaining Water Levels in: • Water Storage Tanks • Water Cooling Towers • Air Conditioning Systems • High Pressure Cleaning Systems • Animal Drinking Troughs • Irrigation Applications • High flow • Compact robust construction • Mounts horizontally or vertically • Made from corrosion resistant materials • Shuts down slowly to minimise water hammer • 20 - 60mm (¾” - 2 ½”) water level differential (increases as water inlet pressure increases) • Pressure rating 0.3 - 7 Bar (5 - 100 PSI) • Float position easily adjustable with no tools • Valve has switch to lock it in off position • Has port to connect Frostpro anti freeze device Revised 10/06/2025
