Pressure resistance and deformation prevention: With precision welding technology, the structure is sturdy and can withstand water pressure fluctuations without deformation.
Accurate water level control: By using the principle of buoyancy lever to link valves, real-time response to water level changes, automatic opening and closing of water replenishment/drainage, avoiding overflow or idling. Adjustable design, supporting customized float volume and weight, adapting to different cooling tower capacity requirements.
Sealed and leak proof: EPDM/FKM rubber sealing rings are used internally to prevent leakage and ensure long-term use without failure. Fully enclosed structure, preventing impurities from jamming and reducing maintenance frequency.
Wide applicability: Compatible with mechanical and electronic water level control systems, suitable for various cooling towers, circulating water tanks, boilers and other equipment.
Provide multiple interface options for threads/flanges, with flexible installation.
Low maintenance and long service life: Stainless steel material is rust resistant, with no vulnerable parts, and can maintain a long service life even in harsh water quality, reducing operation and maintenance costs.

Stainless steel float balls for cooling towers are mainly used for automated water level control to ensure stable operation of the cooling water system. Its main applications include:
Water level regulation: Real time monitoring of the water level in the cooling tower collection tray or water tank, automatic water replenishment or drainage through linkage valves, to prevent low water level (causing the water pump to idle) or high water level (causing overflow waste).
Anti dry burning protection: In equipment such as boilers and evaporative cooling towers, it avoids dry burning damage caused by water shortage and improves safety.
Circulating water system management: suitable for industrial circulating water cooling towers, central air conditioning condensing systems, etc., to maintain water level balance and ensure heat exchange efficiency.
Chemical and power industries: Its corrosion resistance makes it suitable for cooling water treatment systems in power plants and chemical plants, and for water quality environments containing chemical agents.
Fire water tanks and storage facilities: Expand their application to scenarios such as fire water tanks and industrial water storage tanks, achieve automatic water level control, and reduce manual intervention.

Stainless Steel Cooling Tower Water Float FAQ
Q1.What is the working principle of the stainless - steel float ball of the cooling tower?
A1.The stainless - steel float ball of the cooling tower works based on the principle of buoyancy. When the water level rises, the float ball rises accordingly, and the internal mechanical structure is linked to close the water supply valve; when the water level drops, the float ball sinks, and the valve opens to replenish water, thereby maintaining a stable water level in the cooling tower and ensuring the normal operation of the equipment.
A2.When selecting, factors such as the volume of the cooling tower water tank, the size of the pipe diameter, and the water level control range need to be considered. For water tanks with a large volume and thick pipe diameter, float balls with strong load - bearing capacity and large size are required; at the same time, according to the required water level control height, the stroke range of the float ball linkage structure should be determined to ensure accurate water level control.
A3.The installation of the stainless - steel float ball is relatively simple, and it can generally be operated according to the instructions. However, for large and complex cooling tower systems, it is recommended to have professional personnel install it to ensure that the installation position of the float ball is accurate and the linkage structure is firmly connected, avoiding water leakage or control failure caused by improper installation.
A4.Under normal use, due to its corrosion - resistance and high - strength properties, the service life of the stainless - steel float ball can reach 5 - 8 years. However, if the water quality is poor or the use environment is harsh, such as long - term exposure to strong acids and alkalis, its service life may be shortened.
A5.If water leakage is found in the float ball, immediately close the water supply valve, drain part of the water in the water tank, and take out the float ball for inspection. If the sealing element is aged and damaged, replace it with a sealing element of the same specification; if the main body of the float ball is cracked, replace the float ball with a new one in a timely manner. After replacement, re - commission it to ensure normal operation.
A6.Inaccurate water level control of the float ball may be caused by various reasons. For example, the float ball may be stuck by debris, affecting its normal up - and - down movement; the components of the linkage structure may be loose or worn, leading to control failure; or the float ball may be incorrectly selected, and its load - bearing capacity does not match the actual demand. Each of these factors needs to be investigated and resolved one by one.
A7.Regular maintenance is required. Every 3 - 6 months, check the surface of the float ball for corrosion and damage, and ensure that the linkage structure is flexible. Clean the debris attached to the float ball and its surrounding area. Test the sealing performance of the float ball once a year to ensure its good working condition.
A8.In theory, stainless - steel float balls of different brands can be used interchangeably if their specification parameters (such as size, interface, and linkage structure form) are exactly the same. However, due to differences in manufacturing processes and quality standards among brands, it is recommended to give priority to original factory products or products of the same specification from brands with a good reputation to ensure compatibility and reliability.
A9.The stainless - steel float ball has certain high - temperature resistance and can generally withstand a water temperature of 60 - 80°C. However, if it is in a too high - temperature environment for a long time, the performance of its sealing elements and linkage structure may be affected. When using, it is necessary to ensure that the actual water temperature is within its tolerance range.
A10.The failure of the float ball will affect the operation of the cooling tower. If the float ball cannot control the water level normally, it may cause the water level in the water tank to be too high and overflow, resulting in water waste; or the water level may be too low, causing the cooling tower to be unable to dissipate heat due to lack of water, affecting the cooling effect and even damaging the cooling equipment.
