1/2" Automatic Float Valve for Livestock Water Trough & Bowl

Keep Water Levels Perfect — Automatically

The 1/2" Automatic Water Float Valve is a simple, reliable solution for maintaining consistent water levels in troughs, bowls, and tanks used by cattle, horses, goats, sheep, pigs, dogs, and more. Using the proven floating principle, this valve opens and closes automatically as the water level rises and falls — so you spend less time checking and refilling, and more time on what matters.

Made in Mainland China.

Frequently Asked Questions

Q: What pipe thread size does this automatic float valve use?

A: This livestock float valve features a standard 1/2 inch NPT pipe thread, which is one of the most common thread sizes in plumbing worldwide, making it easy to connect to most water supply lines on farms, ranches, and homesteads.

Q: What animals and applications is this float valve suitable for?

A: This automatic water float valve is designed for a wide range of uses. It works great in water troughs and automatic waterer bowls for cattle, horses, goats, sheep, pigs, dogs, chickens, and other livestock. It is also suitable for aquariums, aquaculture ponds, hydroponic reservoirs, and fish-and-vegetable symbiosis systems.

Q: How does the automatic float valve work?

A: The valve works on a simple floating principle. As the water level drops, the float descends and opens the inlet to allow water in. As the water level rises back to the target level, the float rises and shuts off the water supply automatically — maintaining a constant, consistent water level without any manual effort.

Q: Is this float valve durable enough for outdoor farm use?

A: Yes. The valve is constructed from corrosion-resistant, deformation-free plastic, making it well-suited for outdoor farm and ranch environments. It maintains a tight seal and can handle substantial fluid pressure, ensuring reliable, long-term performance in all weather conditions.
