Keep Your Livestock Water Trough Always Full — Automatically

Say goodbye to manually refilling water bowls and troughs every day. This 3-pack of 1/2" automatic water float valves is engineered for farms and homesteads, ensuring a constant, self-regulated water supply for cattle, horses, goats, sheep, pigs, dogs, and more. When the water level drops, the float drops with it — opening the valve and refilling automatically. When full, the float rises and shuts off the flow. It's simple, reliable, and virtually maintenance-free.

Made in Mainland China from high-quality, durable plastic, these float valves are built to withstand the demands of daily agricultural use.

Versatile Application Fields

These float valves aren't just for animal watering troughs. They work perfectly across a wide range of water management systems, including:

Livestock automatic water bowls (cattle, horses, goats, sheep, pigs, dogs)
Water tanks and water towers
Air coolers and cooling towers
Ice machines and humidifiers
Water purifiers
Other environmental and animal husbandry equipment

Why Choose These Float Valves?

Proper hydration is one of the most critical factors in livestock health and productivity. A consistent, automatically refilling water supply means your animals always have access to fresh water without constant human intervention — saving you time, labor, and worry. The standard 1/2" thread makes installation quick and easy on most commercially available water troughs and tanks.

Frequently Asked Questions

Q: What size pipe or fitting does this automatic float valve connect to?

A: Each float valve features a standard 1/2" thread (20mm) inlet, making it compatible with most common water supply lines, tanks, and troughs used in farm and livestock settings.

Q: Which animals and water systems are these livestock float valves suitable for?

A: These automatic water float valves are designed for a wide range of farm animals including cattle, horses, goats, sheep, pigs, and dogs. They are also suitable for water tanks, cooling towers, ice machines, humidifiers, water purifiers, and other agricultural water management equipment.

Q: Do these float valves require electricity or batteries to operate?

A: No — these are fully mechanical, gravity-operated float valves. No batteries or electrical connection is needed. When the water level drops, the float opens the valve to refill; when the desired level is reached, the float rises and shuts off the flow automatically.
