Vanne flotteur à joint souple résistante aux basses températures AF-89
AF-89 Low Temperature Resistant Soft Seal Float ValveThe AF-89 float valve belongs to the ball valve category. It is a piston valve with a float aded. It uses the lever principle and the rising or falling of the float to control the opening and closing of the piston valve. When the float rises, the piston valve slowly closes; when the float sinks, the piston valve slowly opens, making it a device for controlling water level.
The float valve is made entirely of stainless steel through die-casting technology, which ensures a perfect fit between the components and prevents corrosion, loosening, or jamming. This ensures that the ball valve can work stably for a long time. At the same time, the stainless steel components prevent chemical corrosion in high-humidity environments, keeping the drinking water pure and healthy.
The float valve features a unique dual-rod buoyancy transmission, which significantly increases the buoyancy of the ball, achieving a sealing pressure of over 8 kg, far exceeding the national standard of 6 kg. Combined with a vertical valve core for stable transmission, this comprehensively solves the problem of float valves easily failing due to unbalanced force on the valve core, ensuring the reliable operation of the float valve.

AF-89 Low Temperature Resistant Soft Seal Float Valve Application characteristics
KOZO VALVE’s float valves utilize hydraulic design principles, featuring a lightweight structure, reliable opening and closing actions, high sensitivity, low head loss, and no water hammer. They are also characterized by their light weight, small size, and convenient installation and maintenance. KOZO VALVE’s quality – honed over ten years – is unmatched in the market. Widely applicable to automatic water supply systems in industrial and mining enterprises, and civil buildings for various water tanks, pools, and towers, they can also be used as control valves for circulating water supply in atmospheric pressure boilers.
AF-89 Low Temperature Resistant Soft Seal Float Valve Working principle
Working principle of float valve: When the water level in the pool (tower) drops, the float falls, and the pressure of the water in the pipeline opens the sealing surface of the ball valve, and the valve body opens to supply water. When the water level in the pool (tower) rises, the float rises, drives the small plunger, closes the small hole, and the sealing surface is sealed, and the valve stops supplying water.
