Automatic Water Level Control Float Valve, Top Inlet Water Shut Off Valve 🛠️
Keep filling water under control 💧
This top-inlet float valve mechanically shuts off incoming water when the tank reaches its set level.

For water storage that needs a reliable stopping point
Designed for water tanks, water towers, and cooling circulation systems in farm, workshop, and industrial settings.
A straightforward mechanical approach to everyday water management.
Four checks for a considered setup 🛠️
Start with the connection and operating conditions of your existing system.

-
STEP 1📏
Check connector size
Compare your connection with the listed 0.79-inch and 0.98-inch options.
-
STEP 2🔎
Verify thread compatibility
Confirm both thread type and size before choosing a valve.
-
STEP 3📍
Review the inlet position
Check that your intended installation accommodates a top-inlet valve at the required water level.
-
STEP 4🌡️
Review water temperature
Compare your operating conditions with the stated hot-water limit of 100°C.
Concrete details behind the control
The valve combines buoyancy-based shutoff with a stainless steel body.

Mechanical actuation
A buoyancy-based mechanism controls automatic water shutoff.
SUS304 stainless steel
The specified body material provides a corrosion-resistant structure.
Top-inlet configuration
The incoming water connection uses the top-inlet layout identified for this valve.
Thread sealing tape included
A roll of PTFE tape is supplied to help seal threaded connections.
Three places to put level control to work
Choose an application that matches the valve's connection and operating requirements.

Water storage tanks
Control incoming fill water at the tank's set height.
Water towers
Use mechanical level control in a compatible water tower setup.
Cooling circulation systems
Manage water replenishment in a compatible cooling system reservoir.
Built around practical operating needs
Its strongest features address power access, water exposure, temperature, and installation.

-
🔋
Independent of electrical power
The level-control mechanism operates without an electrical connection.
-
☔
Suited to damp settings
The corrosion-resistant body suits humid, water-rich working environments.
-
🔥
Hot-water capability
The stated temperature support extends to water up to 100°C.
-
🔧
Two connection choices
Select the listed connector size that matches your installation requirements.
Less time watching the water rise
Two grounded settings where automatic fill shutoff can simplify routine work.

At a farm storage tank
During a tank fill, the valve stops incoming water at the set height, reducing the need to watch the entire refill.
Beside a workshop reservoir
For a compatible workshop water setup, mechanical control handles the fill stopping point without needing electrical power.
A purposeful addition to a water setup
Consider this valve when planning maintenance, a replacement, or a new installation.

Tank maintenance
Consider automatic shutoff when reviewing how your existing storage tank fills.
Valve replacement
Compare connector size, thread type, and inlet layout with the valve being replaced.
New system planning
Account for top-inlet placement and the intended water height before installation.
Two listed sizes, one essential fit check
Match the connector and thread requirements of your system before selecting.
0.79-inch connector
Choose this listed option when its size and thread specification match your connection.
0.98-inch connector
Choose this listed option when your installation calls for the larger connector and matching threads.
For people responsible for keeping water contained
A practical option for compatible storage and circulation setups.
Farm operators
For managing fill levels in farm water storage tanks.
Property owners
For a compatible water tank that currently needs manual fill supervision.
Workshop maintainers
For assessing a mechanical shutoff upgrade to a workshop reservoir.
Facility teams
For evaluating level control in water towers and cooling circulation systems.
Key details at a glance
Common questions, clear answers
Does this valve need electricity?
No. It uses a mechanical, buoyancy-based mechanism to shut off incoming water.
When does the water stop?
The valve shuts off incoming flow when the water reaches the set height.
Can it handle hot water?
The stated hot-water limit is 100°C / 212°F. Check the requirements of your complete system before use.
How do I choose a connector?
Compare the listed 0.79-inch and 0.98-inch options with your connection. Verify thread type as well as size; the size label alone does not establish NPT compatibility.
Is thread sealing tape included?
Yes. A roll of PTFE thread sealing tape is included to help form sealed threaded connections.
What applications is it intended for?
The listed applications include water tanks, water towers, and cooling circulation systems, subject to connection and operating compatibility.
Give incoming water a clear stopping point
Bring mechanical automatic shutoff to a compatible water setup with a SUS304 stainless steel, top-inlet float valve.
Choose Connector SizeAvailable with a 0.79-inch or 0.98-inch connector. Confirm thread compatibility before ordering.
