Compact Format with High Flow Rate

The valve features a small, space-saving design. Compared to traditional float valves, it delivers a more stable and efficient water flow within a significantly more compact profile.

Fully Automatic Operation Without Power or Manual Intervention

When the water level in the container drops, the float sinks, allowing supply water pressure to open the plunger and silicone seal to let water in. As the water level rises to the set mark, the float rises and, via the connecting rod, closes the silicone seal against the inlet to shut off water flow automatically. Ideal for automatic level control in water tanks, water towers, pools, reservoirs, solar thermal systems, and livestock drinking troughs. It functions entirely without electricity, requiring only a clean water supply with appropriate operating pressure.

Robust Food-Grade Materials

Constructed from food-grade 304 stainless steel, making it fully safe for drinking water. The solid metal body provides high resistance to wear and mechanical impact, ensuring extended service life in daily use.

Wide Range of Applications

Stainless steel offers superior corrosion and temperature resistance compared to standard plastic valves. This valve is suitable for water storage containers, water towers, pools, solar collectors, and similar water reservoirs. Operation is governed strictly by water pressure (minimum 0.2 bar/kg) with no electrical wiring required.
