Float control valve

The float valve is a mechanical automatic water level controller. It operates without electricity and relies on the buoyancy of the float and lever mechanism to automatically fill and shut off water, effectively preventing tank overflow.
Available in brass, stainless steel and plastic materials with a full range of specifications. It features simple installation, stable performance and long service life, and is widely applied in various water storage scenarios such as water towers, fire water tanks, aquaculture and irrigation.

Detail

Parameters

The float valve is the most classic and widely used mechanical fully automatic liquid level control valve in water supply and drainage systems. Requiring no power supply, electronic control modules or manual intervention, the product fully relies on water buoyancy and lever mechanical structure to automatically control water inflow and cutoff for water tanks, water towers, reservoirs and water storage equipment.

The device can maintain a constant water level automatically around the clock. It effectively solves common problems including traditional manual water replenishment, frequent start-stop of water pumps, tank overflow and water shortage cutoff. Featuring stable performance,

high safety and reliability, long service life and maintenance-free operation, it is widely applicable to various water storage scenarios

such as domestic potable water supply, industrial water treatment, building fire protection, aquaculture, irrigation and water replenishment for mechanical equipment.As a basic automatic water control fitting, the float valve adapts to normal-pressure, low-pressure and

conventional water pressure supply systems. It is an essential automatic control valve for all water storage equipment with great versatilit

and extensive market coverage.

1. Fully Mechanical & Power-Free Operation

The float valve works purely by water buoyancy and lever mechanical principles, requiring no electricity, no electronic control modules, and no wiring. It realizes fully automatic water inlet and cutoff with zero energy consumption, avoiding electrical failure and leakage risks.

2. Automatic Constant Water Level Control

It can intelligently maintain a stable water level around the clock, effectively solving common problems such as tank overflow, water

shortage, intermittent water cutoffs, and frequent pump start stop. It ensures stable and continuous water supply for all water storage

equipment.

3. High Safety & Strong Stability

Adopts pure mechanical structure with no vulnerable electronic components. The valve operates stably for a long time under normal

pressure and low-pressure water systems, free from signal failure, delay or misoperation, providing reliable water level control for fire

protection, industrial and domestic water scenarios.

4. Maintenance-Free & Long Service Life

Available in brass, stainless steel and high-quality plastic materials, featuring anti-rust, anti-corrosion and wear-resistant properties.

The reasonable structural design reduces failure rate greatly, realizing long-term service and zero daily maintenance cost.

5. Wide Compatibility & Easy Installation

With complete specifications and strong versatility, the float valve is suitable for water towers, water tanks, pools, aquaculture, irrigation,

industrial equipment water replenishment and fire water systems. It features simple installation, flexible adaptation to various water

pressure environments, and ultra-wide market applicability.
