What Are The Main Conditions For Using Fluorine-lined Ball Valves?

The use conditions of Lined Ball Valve mainly include medium properties, pressure and temperature range, installation location and method, operation method and maintenance. The following is a detailed analysis of these use conditions:

1. Medium properties

Fluorine-lined ball valves are suitable for pipeline systems with highly corrosive media such as acids, alkalis, salts, organic solvents, such as chemical, petroleum, pharmaceutical, food and other industries. When selecting a fluorine-lined ball valve, you should choose the appropriate valve material and lining material according to the properties of the medium, such as fluorine-lined polypropylene (FEP), fluorine-lined ethylene (PTFE), etc. Different lining materials are suitable for different media and temperature ranges, so they need to be selected according to working conditions.

2. Pressure and temperature range

The operating pressure and temperature range of fluorine-lined ball valves depend on factors such as valve materials and sealing structures. Generally speaking, the operating pressure of fluorine-lined ball valves does not exceed 1.6MPa (some products may reach 2.5.55MPa, but it needs to be determined according to the specific product description), and the temperature range is -20℃~150℃. However, it should be noted that the temperature resistance of different lining materials is also different. For example, the operating temperature range of FEP (F46) is -85℃~150℃, while the operating temperature range of PCTEF (F3) is -195℃~120℃. Therefore, when selecting a fluorine-lined ball valve, the appropriate valve material and lining material should be determined according to the temperature and pressure conditions of the medium.

3. Installation location and method

The installation location of the fluorine-lined ball valve should be selected according to the requirements of the pipeline system. It is generally recommended to install it on a horizontal pipeline. During installation, the switching direction of the valve should also be considered to achieve smooth operation of the valve. In addition, the connection method of the fluorine-lined ball valve is usually flange connection, and other connection methods can also be selected according to user needs (but be careful to avoid welding connection methods). During installation, ensure that the valve is installed in the correct position, the connection is firm, and comply with relevant installation specifications and standards.

4. Operation mode

The operation mode of the fluorine-lined ball valve is usually manual, pneumatic, electric, etc. When selecting the operation mode, it should be selected according to the actual situation. Manual operation is suitable for small pipeline systems or occasions where frequent operation is required; pneumatic and electric operation are suitable for large pipeline systems and automated production lines. In addition, some fluorine-lined ball valves are also equipped with remote control functions, which can realize remote switching operation of the valve through a remote control device.

V. Maintenance

Fluorine-lined ball valves require regular maintenance during use to ensure the normal operation of the valve. Maintenance includes cleaning, lubrication, inspection and sealing. The specific operation method should be selected according to the model and use of the valve. During maintenance, care should be taken to avoid using detergents or lubricants that corrode the valve material, and follow relevant maintenance specifications and standards.

In summary, the use conditions of fluorine-lined ball valves involve multiple aspects and need to be selected according to specific working conditions and user needs. During use, attention should also be paid to the operation method and maintenance to improve the service life and safety performance of the valve.
