Automatic Water Level Control – No Electricity Needed

Keep your tank, pool, solar system, or aquarium at the perfect water level — automatically. This ½-inch thread float ball valve detects the water level and cuts off the supply when full, then opens again when the level drops. No wiring, no pumps, no manual monitoring required. Made in Mainland China from non-toxic, durable PA6 nylon reinforced with stainless steel, it's built for long-lasting, trouble-free performance.

Key Features

  • Fully Automatic Control: Floats rise and fall with the water level to open and shut the valve — water fills automatically when low, stops when full.
  • No Electricity Required: Operates purely on water pressure (minimum 0.1 kg). Ideal for off-grid setups, solar water systems, and remote locations.
  • Non-Toxic, Durable Material: Constructed from PA6 nylon + stainless steel — corrosion-resistant, food-safe compliant, and rated for temperatures from 0 °C to 70 °C.
  • 4 Configuration Options: Choose the style that fits your installation:
    • ½" Upper water inlet (inner installation) — normal & high-temperature use
    • ½" Side water inlet (inner installation) — normal & high-temperature use
    • ½" Bottom & side water inlets (outer installation) — also compatible with inner installation
    • ½" Upper & bottom water inlets (outer installation) — ideal for solar energy systems; also compatible with inner installation
  • Wide Application: Compatible with water tanks, fish/aquaculture tanks, solar water heaters, pools, livestock troughs, and general automatic water supply systems.
  • Easy DIY Installation: Compact, lightweight design with a standard ½" (20 mm) thread — fits most common tank fittings without specialist tools.

Frequently Asked Questions

Q: What types of tanks or containers is this float ball valve compatible with?

A: This automatic water level control valve is compatible with a wide range of containers including water storage tanks, aquariums, aquaculture breeding tanks, solar water heater tanks, livestock troughs, pools, and any vessel with a standard ½-inch (20 mm) threaded fitting. Both inner and outer installation configurations are available to suit different tank designs.

Q: Does this valve require electricity or a pump to operate?

A: No electricity or external pump is needed. The float ball valve operates entirely on water pressure — as long as the incoming water pressure is at least 0.1 kg, the valve will open and close automatically based on the water level, making it ideal for off-grid, solar, and remote installations.

Q: How do I choose the right configuration for my setup?

A: Select based on where your water inlet is located and whether you need internal or external installation. Upper and side inlet types are designed for inner (inside the tank) installation and handle both normal and high temperatures. Bottom & side and upper & bottom inlet types are designed for outer installation but are also compatible with inner installation — the outer types are especially popular for solar water heater systems.

Q: Is the material safe for drinking water or food-grade applications?

A: Yes. The valve is constructed from non-toxic, environmentally safe PA6 nylon combined with stainless steel components, making it safe for potable water storage applications. Always verify compatibility with your local water quality standards before installation in drinking water systems.
