Automatic Water Level Control Float Valve - Mini Mechanical Shut-Off Valve for Water Tanks & Towers

Keep water levels under control automatically with this electricity-free float valve, designed to regulate water flow in tanks, water towers, animal drinking systems, garden projects, fountains, rainwater collection containers, and other compatible water reservoirs. The simple float mechanism uses water buoyancy to open and close the valve automatically as the water level changes.

As the water level rises, the internal float lifts and shuts off the incoming water. When the level drops, the valve opens again to replenish the tank. No electricity, sensors, or smart controls are required, making it a practical solution for automatic water-level management.

Key Features:

• Fully automatic water level control

• No electricity or batteries required

• Automatic water flow shut-off and refill

• Compact mini float valve design

• 1/2-inch male BSP thread

• Nylon valve body with stainless steel screws

• Includes inlet filter to help prevent debris from blocking the float

• Suitable for water tanks, water towers, fountains, garden projects, rainwater collection, and animal watering systems

• Operating water pressure: 10–150 PSI

• Operating temperature: 0–60°C

• Easy installation and maintenance

Important: Verify your water pressure and thread compatibility before installation. For indoor installations, an appropriate emergency overflow system is recommended to help prevent water damage in the event of valve failure. The inlet filter should be used to reduce the risk of sand or debris interfering with the float mechanism.
