Float Valve Automatic Stainless Steel 304 No Power Needed for Water Tank Cistern Control | Sansoti

Automatic Float Valve – Self-Regulating Water Level Control

This automatic float valve regulates the water level in your tank, cistern, or storage system completely independently. No electricity required, no manual operation, and no constant supervision—the valve opens and closes at precisely the right moment based on the mechanical float position. Made from high-quality 304 stainless steel with food-grade certification, this valve is resistant to corrosion, rust, and extreme temperatures. The compact design fits into tight installation spaces, the operating pressure reaches up to 10 bar, and the temperature tolerance of 0 to 100 °C makes it suitable for cold water, hot water, and solar water heating systems. Available in four connection diameters, allowing you to seamlessly integrate the valve into virtually any piping network.

Benefits of the Float Valve

• Fully automatic operation without electricity: The valve responds immediately to the float level and opens or closes automatically without requiring any settings or programming.
• Food-grade 304 stainless steel: The material is approved for drinking water systems and offers excellent resistance to acids, chemicals, and oxidation.
• Wide range of applications: From rainwater tanks and IBC containers to solar water heaters and ponds—the valve is suitable for various water management systems.
• Operating pressure up to 10 bar and temperature range of 0–100 °C: Suitable for both cold- and hot-water applications, offering high reliability under demanding conditions.
• Compact and easy to install: The small dimensions and availability in four connection sizes make installation in tight spaces possible without complex modifications.
• Low maintenance and durable: The absence of moving electronics means fewer potential failures and a longer service life.

Designed for Reliable Water Level Control

Whether you manage a rainwater storage system, fill a solar water heater, or want to automatically refill a cistern, this float valve solves the problem of overflow or dry running without requiring your attention. The mechanical system responds immediately to changes in the water level, ensuring that your reservoir always contains the right amount of water. Thanks to its rust-resistant construction, the valve continues to operate reliably for years, even in outdoor installations or damp basements. The four available connection options—1/2-inch and 3/4-inch with top connection or side inlet—allow you to choose the configuration that best suits your pipework. For a watertight connection, simply wrap Teflon tape around the thread. This prevents overflow, protects your installation, and provides worry-free water convenience at home, in the garden, or on commercial premises.
