SMART WATER MANAGEMENT · AUTOMATIC REFILLING · RELIABLE CONTROL
Automatic Water Level Control Valve
Maintain a consistent water level without constant monitoring. This automatic float valve intelligently controls water flow, refilling your tank when the water level drops and automatically stopping the supply once the desired level is reached. No electricity or complicated controls required.
SMARTER WATER LEVEL MANAGEMENT
Automatic Water Control Made Simple
Say goodbye to constantly checking and manually refilling your water tanks. This compact automatic water level control valve uses a built-in floating mechanism to regulate water flow according to the water level.
When the water level drops, the valve automatically opens to replenish the supply. Once the water reaches the preset level, the floating mechanism rises and shuts off the incoming water. Enjoy convenient, consistent water management with a simple mechanical design.
01 / AUTOMATIC WATER CONTROL
Intelligent Automatic Refilling
Enjoy hassle-free water management with an automatic refill mechanism. When the water level in your tank, water tower, or livestock drinking system falls below the preset level, the float valve automatically opens to allow fresh water to flow in.
As the water rises to the designated level, the internal float moves upward and automatically stops the water supply, helping maintain a consistent water level without manual operation.

02 / SIMPLE INSTALLATION
Easy Installation with Standard Thread Connections
Designed with a compact body and extended male threaded connections, this mini float valve is convenient to install in various water tank and plumbing applications.
Available with 1/2-inch and 3/4-inch male thread options, it is designed for compatibility with common BSP threaded connections. For NPT threaded connections, PTFE thread-sealing tape can be applied where appropriate to help achieve a secure connection.

03 / ELECTRICITY-FREE DESIGN
Reliable Mechanical Operation Without Electricity
No batteries, wiring, or electrical connections are needed. The internal ball float uses natural buoyancy to control the water supply.
When the water level rises, the floating mechanism moves upward and closes the valve. When the water level drops, the float moves downward and reopens the water passage. This automatic mechanical cycle provides convenient water level regulation whenever needed.

04 / VERSATILE APPLICATIONS
Suitable for a Wide Range of Water Systems
This versatile automatic water level valve is suitable for various residential, agricultural, and outdoor water management applications.

05 / WIDE WORKING PRESSURE RANGE
Designed for Reliable Water Flow Control
The float valve is designed to operate within a water pressure range of 10 PSI to 150 PSI, providing flexible application options for compatible water supply systems.
Maintaining the recommended operating pressure is essential for proper float movement and dependable water flow control. Always check your water system pressure before installation.

06 / BUILT-IN FILTRATION
Integrated Filter for Easier Maintenance
The built-in filter helps catch sand and small particles before they enter the valve mechanism. This helps reduce the risk of debris accumulation and blockage, supporting smoother water flow and more convenient routine maintenance.
Regularly inspect and clean the filter to maintain reliable operation, especially when using water from outdoor storage tanks or rainwater collection systems.

07 / STAINLESS STEEL CONSTRUCTION
Durable Stainless Steel Valve Body
Manufactured with a stainless steel valve body and stainless steel screws, this float valve is designed for dependable everyday use. Its metal construction offers corrosion resistance and durability in suitable water system environments.
The compact, rounded design combines practical functionality with a sturdy construction, making it a convenient addition to a variety of water management setups.
