Made by \u003cstrong\u003eJobe Valves of New Zealand\u003c\/strong\u003e, the Topaz is a proven choice for cattle, horse and sheep producers who need fast refills, a compact and robust valve, and dependable shut-off in real farm and ranch conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe Topaz works differently from a basic float valve. The float operates a small pilot valve, which in turn operates the \u003cstrong\u003emain diaphragm valve\u003c\/strong\u003e — so you get high flow when the trough needs water and a \u003cstrong\u003egradual close that helps reduce water hammer\u003c\/strong\u003e in your lines. Water level stays within a 3\/4\"–2-1\/2\" range, adjusting with inlet pressure.\u003c\/p\u003e\n\n\u003cp\u003eChoose the size and tail that fit your setup. The Topaz is available in \u003cstrong\u003e3\/4\", 1\" and 1-1\/4\" inlets\u003c\/strong\u003e, with \u003cstrong\u003elong tail\u003c\/strong\u003e options supplied with a backnut and seal washer for through-wall mounting, \u003cstrong\u003eshort tail\u003c\/strong\u003e options for a low-profile connection, and a \u003cstrong\u003e1\" Detach\u003c\/strong\u003e model on Jobe's Detach base, compatible with the Detach Outlet Extension (sold separately). Larger inlets deliver more flow at the same pressure, making the 1\" and 1-1\/4\" a strong fit for big troughs and high-demand watering points.\u003c\/p\u003e\n\n\u003cp\u003eBuilt from \u003cstrong\u003ecorrosion-resistant materials\u003c\/strong\u003e — a glass-filled nylon body, 304 stainless steel hardware and an HDPE float — the Topaz is made for daily use in the pasture.
