Automatic Float Valve with Stainless Steel Float for Water Tanks – Pressure Controlled Without Power | Sansoti

Self-regulating water level protection for every storage system

Your water tank, rainwater cistern, or storage system deserves reliable protection against overfilling. This float valve fully automatically regulates the water level based on the float position of the built-in float – without power supply, manual adjustments, or constant supervision. Thanks to the mechanical operation based on water pressure, the valve opens and closes precisely when needed, saving water and preventing water damage. Made of corrosion-resistant stainless steel 304, suitable for drinking water, solar boilers, and hot water systems up to 100 °C. With its compact design and four connection sizes, this valve fits almost any installation situation, from rainwater cisterns to agricultural storage tanks.

What makes the difference in your storage system

• Pressure-driven mechanical system: operates completely independently based on water pressure differences and float position – no electricity or batteries needed
• Food-safe stainless steel 304: corrosion-, rust-, and heat-resistant material, safe for drinking water systems and long-term outdoor storage
• Universally applicable: suitable for water tanks, solar hot water systems, rainwater cisterns, irrigation systems, and storage basins
• Four connection sizes: available in 1/2" and 3/4" top or side connections for flexible installation in any system
• Wide pressure and temperature range: reliable from 0 to 10 bar and temperatures from 0 to 100 °C – suitable for cold and hot water installations
• Easy installation: mount directly on existing threaded connections, sealing with Teflon tape is sufficient

Designed for sustainable water management

Whether you manage a rainwater storage system, fill a solar boiler, or maintain an irrigation network – this float valve offers low-maintenance reliability without power costs. The sturdy stainless steel mechanism provides years of dependable performance, even with frequent filling cycles or fluctuating water pressure. The float responds immediately to changing water levels and smoothly switches the valve on or off. Thanks to the compact design, it also fits into narrow shafts or hard-to-reach mounting positions. Ideal for those who value reliable automation without complex electronics.
