Adjustable Auto-Fill Float Ball Valve for Water Tanks & Towers

Adjustable Auto-Fill Float Ball Valve for Water Tanks & Towers

Keep your water tank, tower, aquarium, or storage reservoir at the perfect level — automatically. This Gmarty adjustable float ball valve uses proven buoyancy technology to open and close your water supply with zero manual effort. When the water rises to your set level, the floating arm lifts and shuts the valve; as the level drops, it opens again for a continuous, hands-free fill cycle.

Made in Mainland China.

Key Features

• Fully Automatic Control: Float rises and falls with the water level, opening and closing the valve without any manual intervention.
• Adjustable Design: Flexible arm allows easy fine-tuning of the cut-off water level to suit any tank size or application.
• High Flow Rate: Wide-bore design delivers strong, efficient water flow for faster tank filling.
• Easy Installation: Can be mounted at virtually any angle — no specialist tools required.
• Non-Toxic & Tasteless POM Material: Durable POM (polyoxymethylene) construction is corrosion-resistant, food-safe, and built to last in wet environments.
• Versatile Use: Ideal for water towers, storage tanks, household cisterns, aquariums, chemical tanks, and agricultural troughs.
• Water-Saving: Precise cut-off prevents overflow and reduces wasted water.

Frequently Asked Questions

Q: What is a float ball valve and how does it work?

A: A float ball valve is an automatic water level control device. A buoyant float sits on the water surface and is connected to a valve via a rod. As the water level rises, the float rises too, pushing the rod upward until it reaches the set point and closes the valve to stop the water supply. When the water level drops, the float lowers and reopens the valve to refill the tank — fully automatic and hands-free.

Q: What tanks or applications is this float valve suitable for?

A: This adjustable float ball valve is suitable for a wide range of applications including rooftop water towers, storage cisterns, household water tanks, aquariums, livestock troughs, chemical storage tanks, and irrigation reservoirs. Its corrosion-resistant POM material makes it versatile across both domestic and light industrial uses.

Q: How do I adjust the water cut-off level?

A: Simply bend or reposition the float arm to change the angle at which the float triggers the valve closure. A higher float position raises the cut-off water level; a lower position lowers it. The valve can also be installed at various angles to accommodate different tank configurations.

Q: Is the material safe for drinking water tanks?

A: Yes. The valve is made from POM (polyoxymethylene), a non-toxic, tasteless, and food-grade engineering plastic that is safe for potable water systems and resistant to corrosion and chemical exposure.
