DN15 1/2 Inch Plastic Float Valve – Auto Water Level Control
DN15 1/2 Inch Plastic Float Valve – Auto Water Level Control
DN15 1/2 Inch Spool Box Float Valve – Automatic Water Level Control
Keep your water tank, aquarium, livestock trough, or storage cistern perfectly filled without constant monitoring. This DN15 1/2 inch plastic float valve automatically shuts off water flow when the desired level is reached, then opens again as the level drops — no electricity, no manual intervention required.
Key Features
- Fully Automatic Operation: The buoyant float rises with the water level and mechanically closes the valve, preventing overflow and water waste.
- Versatile Compatibility: Suitable for drinking water, household tanks, aquariums, chemical storage, and corrosion-prone environments thanks to its non-toxic, odorless plastic construction.
- Easy Adjustable Angle: Can be installed at virtually any angle for flexible positioning in any tank or reservoir configuration.
- Wide Pressure Range: Rated for 0.1–1.2 MPa, making it suitable for both low-pressure gravity-fed systems and standard pressurized supply lines.
- Temperature Rated: Operates in water temperatures from 0°C to 70°C (32°F to 158°F).
- Lightweight & Durable: Made from high-quality white plastic; weighs just 60 g for easy handling and installation.

Frequently Asked Questions
Q: What pipe size is this float valve compatible with?
A: This float valve is designed for DN15 / 1/2 inch connections, one of the most common pipe sizes for household and light-commercial water tanks. Always verify your tank's inlet connection size before ordering.
Q: Can this float valve be used for drinking water tanks?
A: Yes. The valve is made from non-toxic, odorless plastic, making it safe for use in potable (drinking) water storage systems, as well as aquariums, chemical tanks, and general household cisterns.
Q: How do I adjust the water level it cuts off at?
A: The float arm can be bent slightly or repositioned to raise or lower the cut-off water level. Because the valve can be installed at any angle, it offers flexible adjustment to suit different tank depths and configurations.
Q: What is the maximum water pressure this valve handles?
A: The float valve is rated for working pressures between 0.1 MPa and 1.2 MPa, covering most standard mains and gravity-fed water supply systems.
