Float Valves, ball cocks, trough valves, ball valves, these are different names used for the valve used to fill water tanks, water troughs, stock waterers and water storage tanks. 

Jobe Valves specialise in the manufacture of these valves for use in agriculture and in light industry. The  main Jobe brands are Megaflow Trough Valves and Topaz Trough Valves for use when high flow is of top importance, and Rojo Float Valves for use when flow is not so important but adaptability over a wide pressure range and potential uses is.

Agricultural applications include supplying drinking water for dairy cattle, sheep and other livestock, cooling systems in poultry sheds, filling water storage tanks.

Light Industrial applications include supplying water to evaporative cooling systems, cleaning systems, car washes and anywhere a water tank needs to be filled by a valve that closes when that tank is full.
