Automatic Float Ball Valve 1/2" 3/4" 1" Water Level Control
Automatic Float Ball Valve – Precise Water Level Control for Tanks & Towers
Keep your water storage tank, tower, or reservoir at the perfect level with this reliable Automatic Float Ball Valve. Available in three standard thread sizes — 1/2", 3/4", and 1" — this hydraulic shutoff valve automatically opens to refill when the water level drops, then closes when the set level is reached. No electricity required; it operates entirely on hydraulic pressure, making it a worry-free, energy-efficient solution.
Made in Mainland China.
Key Features
- Three Size Options: Choose 1/2", 3/4", or 1" NPT thread to match your existing plumbing setup.
- Durable PA66 Plastic Construction: High-strength, corrosion-resistant nylon material stands up to continuous water contact and high temperatures up to 120°C.
- Wide Pressure Range: Operates reliably across 0.2 kg – 10 kg pressure, suitable for most domestic and light commercial water systems.
- Fully Hydraulic (No Power Needed): Completely mechanical operation — no wiring, no electronics, no batteries.
- Automatic Shutoff Mechanism: Float rises with water level and automatically cuts off supply when the target level is reached; reopens when water drops below the set line.
- CE Certified: Meets standard safety and quality certifications.
- Suitable for Pure Water: Designed for clean/pure water media applications.
- Easy Installation: Threads directly into standard tank fittings — installs inside the tank or tower with no special tools required.

How It Works
The float ball sits on the water's surface inside your tank. As the water level falls below the preset control line, the float descends, pulling the valve arm open and allowing water to flow in. Once the water rises back to the control line, the float lifts, pushing the valve arm shut and stopping the water supply automatically — a simple, elegant, and reliable cycle.
Maintenance Tips
In areas with hard or mineral-rich water, periodic cleaning of the valve seat and float arm is recommended to ensure smooth operation and long service life.
