Keep your water tank, tower, garden fountain, or pool at the perfect level — completely automatically. This 304 stainless steel float valve opens and closes on its own using simple buoyancy mechanics, with no electricity required. Compact, corrosion-resistant, and compatible with standard 1/2" and 3/4" threaded connections, it's the reliable, set-and-forget solution for effortless water level management.

Made in Mainland China.

Key Features

• 304 Stainless Steel Construction: Durable, rust-resistant, and built to last in both indoor and outdoor wet environments. Compact size (20 × 70 × 48 mm) makes installation easy in tight spaces.
• Fully Automatic Operation: When the water level drops below the valve, the float descends and opens the valve to refill. Once the water reaches the set level, the float rises, closing the valve automatically — no manual intervention needed.
• 100% Electricity-Free: Operates entirely on water buoyancy. No wiring, no power source, no running costs — just pure mechanical efficiency.
• Built-In Inlet Filter: An integrated filter at the water inlet screens out sand, grit, and debris to prevent clogging and extend the valve's service life.
• Wide Compatibility: Suitable for water tanks, water towers, garden waterfalls, garden fountains, swimming pools, livestock troughs, and more. Compatible with most standard threaded connections (1/2" or 3/4").
• Easy Installation: Simple threaded fitting — no special tools required. Includes 1× Raw Material (PTFE thread seal) Belt to ensure a leak-free connection.
