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.
For maintaining water levels in animal drinking troughs, water storage
tanks, water cisterns, air conditioning systems, high pressure cleaning
systems and irrigation applications.

▪Mounts horizontally or vertically
▪Made from corrosion-resistant materials
