The Gallagher 3/4" Brass Valve with Float is a rugged, submersible solution for automatic livestock water tank management. Designed to maintain consistent water levels in stock troughs and tanks, this valve opens and closes automatically as the float rises or falls—delivering fresh water when animals drink and shutting off when full. Made from corrosion-resistant brass, it handles high flow and pressure without leaking or seizing. The flexible cord and submersible float design hug the wall of the trough, keeping moving parts out of reach of curious livestock and minimizing wear from kicks, bumps, and rough use. It's compatible with standard 3/4" inlets and installs easily in poly, steel, or concrete tanks. Whether you're watering cattle, horses, goats, or other animals, this Gallagher float valve offers low-maintenance, high-reliability performance that stands up to daily ranch use.
