Application

Water Tanks & Reservoirs

For automatic water level control in residential, commercial, and industrial storage tanks.

Solar Water Supply Systems

Maintains stable water levels in solar water heaters and water supply systems.

Water Towers & Replenishment Systems

Automatically controls filling and replenishes water when the level drops.

Cooling & Hot Water Systems

Suitable for cooling towers, boilers, and hot water applications requiring automatic water level control.

Industrial & Agricultural Water Systems

Ideal for industrial water storage, agricultural irrigation, and other automatic water supply applications.

Description

The Plastic Top Inlet Solar Magnetic Automatic Water Level Control Valve is a fully automatic float valve designed for water tanks, water towers, reservoirs, and solar water supply systems. Using magnetic float control technology, it automatically stops water flow when the tank is full and resumes filling when the water level drops. No electricity is required, making it energy-saving, safe, and reliable for long-term automatic water level control. The top inlet structure is suitable for vertical water inlet piping systems, while the PA66 nylon valve body provides strong corrosion resistance, temperature resistance, and long service life.

Equipped with a dual filtration system and enlarged water inlet filter, the valve helps provide cleaner water flow and improved anti-blocking performance. The screw-free buckle housing allows easy disassembly, cleaning, and maintenance. Available in internal and external installation versions with multiple size options, the internal type is installed directly inside the tank or water tower, while the external type is mounted outside and connected through a hose for synchronized water level control.

What is a solar magnetic automatic water level control valve used for?

The solar magnetic automatic water level control valve is designed for automatic water level control in water tanks, solar water systems, and storage containers. It is widely used in: Solar water heaters Household water tanks Rooftop water tanks Automatic water supply systems Industrial water storage systems Agricultural irrigation systems The valve automatically controls water inlet and shuts off water flow when the tank reaches the preset level.

How does the valve work?

The valve operates automatically through water pressure and a magnetic float mechanism. When the water level drops: The float moves downward The valve opens automatically Water enters the tank When the water level rises: The float rises with the water The magnetic mechanism closes the valve Water flow stops automatically No external power supply is required.

What are the main features of this valve?

Main features include: Fully automatic water level control No external power supply required Magnetic control structure Automatic shut-off function Overflow prevention Stable operation Easy installation Long service life Energy-saving operation It helps reduce water waste and improve water management efficiency.

Does the valve require electricity?

No. The valve uses a purely mechanical magnetic float system and does not require: External power supply Wiring Electronic sensors Controllers This makes it suitable for outdoor and energy-saving applications.

Can it prevent water overflow?

Yes. The valve automatically shuts off water flow when the tank reaches the preset water level. This helps: Prevent overflow Reduce water waste Protect tanks and pipelines Improve water management efficiency

What liquids is it suitable for?

The valve is mainly suitable for clean water systems. Suitable media include: Tap water Domestic water Purified water Non-corrosive liquids It is not recommended for: Corrosive liquids Steam Heavy sludge Liquids containing large particles

Can the valve work under low water pressure?

The valve requires a certain water pressure to operate properly. Extremely low water pressure may affect: Automatic shut-off performance Water refill speed Valve sealing performance Buyers should confirm working pressure before installation.

Is it suitable for solar water heater systems?

Yes. The valve is widely used in solar water heater systems because it can automatically replenish water and maintain stable water levels without electricity. It is especially suitable for rooftop water tanks and household water systems.

Can the valve be customized?

Yes. Customization options may include: Connection size Installation structure Material Inlet direction OEM logo and packaging This helps meet different project and market requirements.

What should buyers confirm before ordering?

Before purchasing, buyers should confirm: Material type Installation type Inlet direction Connection size Working pressure Water quality Installation space Quantity and OEM requirements This helps ensure correct installation and compatibility.

What are the advantages of the plastic type?

The plastic type uses engineering plastic materials with advantages such as: Lightweight structure Corrosion resistance Cost-effective design Easy installation Suitable for household water systems It is widely used in residential and general water tank applications.

What are the features of the top inlet type?

The top inlet type allows water to enter from the upper side of the valve. Advantages include: Suitable for top pipeline layouts Cleaner piping arrangement Stable water flow control Suitable for overhead water tanks
