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.

After buying several expensive floats that couldn't handle pressure and gpm, I found these. They are exactly what they're supposed to be and they don't corrode in high sulfur water.
