Topaz 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. Topaz trough valves are a good choice where their high flow, compact, robust, non corrosive construction
and high level of adaptability are needed.
