304 Stainless Steel Automatic Water Level Float Valve - 1 Inch

Maintain a stable water level and help prevent overflowing with this 1 Inch Automatic Water Level Control Valve, a reliable choice within our Hydraulic Valves collection. Made from food-grade 304 stainless steel, the compact internal float mechanism automatically opens the water supply when the level drops and closes it when the tank reaches the required level. Unlike traditional float valves with a long external arm and ball, this space-saving design contains the float mechanism inside the valve body. It is ideal for smaller tanks or installations where limited space is available. The valve operates mechanically using water pressure, so it requires no electricity, wiring or manual switching. A roll of thread-seal tape is included to assist with installation.

How It Works:

When the water level drops, the internal float lowers and opens the inlet, allowing water to enter the tank. As the water level rises, the float moves upward and gradually closes the valve. Once the required level is reached, the water supply stops automatically.
