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.
