304 Stainless Steel Float Valve – Auto Water Level Control
304 Stainless Steel Float Valve – Auto Water Level Control
Automatic Water Level Control – Set It & Forget It
Keep your water tower, storage tank, or reservoir perfectly filled at all times with this 304 Stainless Steel Float Valve. Built for durability and precision, this hydraulic-operated shut-off valve automatically opens when the water level drops and closes when it reaches the set limit — no electricity, no manual intervention required.
Made in Mainland China.
Key Features
- Material: Corrosion-resistant 304 stainless steel body for long-lasting performance
- Available Port Sizes: 1/2", 3/4", and 1 inch to suit a wide range of tank setups
- Hydraulic-Powered: No electricity needed — operates purely on water pressure
- Normally Open (NO): Opens automatically when water level falls, closes when the limit is reached
- Inside-Mount Design: Installs vertically inside the tank for a clean, compact setup
- Operating Pressure: Works within 0.2 kg (min) to 10 kg (max) water pressure range
- Standard Temperature Media: Designed for normal-temperature water applications
- Low-Pressure Compatible: Ideal for gravity-fed tanks and low-pressure water systems
How It Works
As the water level in your tank rises, the float rises with it until it reaches the preset water limit line — automatically closing the valve and stopping the water supply. When the water level drops, the float descends and the valve opens again to refill the tank. It's a simple, reliable, self-regulating system.
Installation Instructions
- Install the valve vertically on a level surface inside the tank.
- Match the inlet pipe diameter to the valve port size before connecting.
- Ensure all stop valves are fully opened before initial use.
- If fitting two valves in one tank, keep both at the same level.
- Flush and clear any impurities from the pipeline before use.
- Note: A small amount of dripping from the valve bottom during operation is normal.
Maintenance Tips
If your water supply contains impurities, periodic maintenance is recommended. If you notice the tank taking longer to fill or the valve not closing automatically, remove and clean the valve to restore full performance.
Ideal For
- Water towers and rooftop storage tanks
- Agricultural and irrigation holding tanks
- Livestock water troughs
- Industrial and commercial water management systems
- Residential water storage solutions

Frequently Asked Questions
Q: What port sizes does this stainless steel float valve come in?
A: This automatic water level control float valve is available in three port sizes — 1/2 inch, 3/4 inch, and 1 inch — making it compatible with a wide variety of water tank and tower setups. Be sure to match your inlet pipe diameter to the valve size you select.
Q: Does this float valve require electricity or a power source to operate?
A: No. This float valve is entirely hydraulic-powered, meaning it operates solely on water pressure — no electricity, wiring, or batteries needed. It works automatically using the natural movement of the float in response to changing water levels.
Q: What water pressure range is this valve compatible with?
A: The valve operates within a water pressure range of 0.2 kg (minimum) to 10 kg (maximum). It is best suited for low-pressure systems such as gravity-fed water towers and storage tanks at normal temperature.
Q: Can I install two float valves in the same water tank?
A: Yes, you can install two valves in a single tank. When doing so, ensure both valves are positioned at the same level surface to maintain consistent and accurate water level control.
