Summary of Ball Valve Application Scenarios, Selection Guide and Maintenance Points

Typical application scenarios of ball valves
With its comprehensive performance, ball valves are widely used in many fields:

1. Industrial field
1）Oil and natural gas: long-distance pipelines, refineries, oil and gas field exploration and other scenarios, used for rapid cutting and transportation of high-pressure fluids.
2）Chemical industry: control corrosive media, toxic and harmful fluids, and ensure the safety of chemical production.
3）Power industry: used in steam systems and water circulation systems to achieve efficient on-off control.
4）Metallurgy and papermaking: It is suitable for working conditions with high temperature and particle-containing media, and can stably transport production fluids.
2. Civil and municipal fields
1）Building water supply and drainage: water supply and drainage systems of residential and commercial buildings to ensure reliable connection and disconnection of pipelines.
2）Gas pipeline: urban gas transmission and distribution to ensure the safety of gas use.
3）Sewage treatment: Treats sewage media containing impurities, with anti-clogging and easy-to-clean properties.
4）Firefighting system: Emergency cut off the fire water source, respond quickly, and ensure fire safety.
3. Special areas
1）Pharmaceutical industry: Use sanitary ball valves to transport clean media and comply with GMP standards.
2）Food processing: Adapt to food-grade fluids to avoid contamination and ensure food safety.
3）Aerospace: used in high-pressure fluid control systems to meet reliability requirements under extreme working conditions.

Ball valve selection and maintenance recommendations

1. Selection guide
Scientific selection is the key to ensuring long-term stable operation of ball valves. We need to focus on the following three points:
1）Matching medium characteristics: For clean water, gas and other media, soft-sealed ball valves should be preferred to achieve zero leakage; for high-temperature and highly corrosive media, hard-sealed ball valves should be selected to improve durability.
2）Determine the driving method: manual ball valves can be used for small flow and low-frequency operation scenarios, which are lower cost; pneumatic or electric ball valves are recommended for automated control and remote operation requirements to improve efficiency.
3）Match working condition parameters: According to the pipeline pressure and temperature level, select the ball valve corresponding to the pressure level and material to ensure that the equipment can safely adapt to the working conditions.
2. Maintenance points
Regular maintenance can effectively extend the service life of ball valves and reduce the risk of failure:
1）Regular inspection: focus on checking whether there is leakage at the valve seat and valve stem packing, and promptly discover and deal with sealing problems.
2）Lubrication and maintenance: Regularly add grease to the valve stem and ball to reduce friction and jamming and improve opening and closing flexibility.
3）Cleaning and dredging: In scenarios containing particulate media, clean the sphere and flow channel regularly to prevent impurities from accumulating and causing blockage.
4）Component replacement: timely replace worn valve seats, packings and other sealing components to ensure sealing performance and system safety.
