Automatic Stainless Steel Float Ball Valve 1/2 & 3/4 Water Tank

Stainless Steel Automatic Float Ball Valve for Water Tanks & Towers

Keep your water tank, tower, pool, or fountain at the perfect level — automatically and without electricity. This compact 304 stainless steel float ball valve uses simple buoyancy mechanics to open and close your water supply, giving you effortless, hands-free water level control.

Key Features

• Premium 304 Stainless Steel Construction: Durable, corrosion-resistant, and built for long-lasting performance in wet environments.
• Fully Automatic Water Level Control: When the water level drops below the valve, it opens to refill automatically. Once the desired level is reached, buoyancy pushes the float up and cuts the flow — no manual intervention needed.
• No Electricity Required: Operates entirely on water pressure and buoyancy — zero energy consumption and no wiring needed.
• Built-in Inlet Filter: Includes a filter at the water inlet to block sand, grit, and debris, preventing clogs and extending valve life.
• Compact & Easy to Install: Small form factor (20×70×48 mm) fits most standard threaded connections (1/2" and 3/4"). Includes 1× raw material sealing belt for a secure, leak-free fit.
• Versatile Applications: Ideal for water tanks, water towers, garden waterfalls, garden fountains, swimming pools, irrigation systems, and more.
