一、运用前，应用水清洗管道和阀体过流部分，以防残留铁屑和其它杂物进入阀体内腔。
二、球阀在封闭状态下，阀体内仍然残留部分介质，也承受着必定压力。在检修球阀之前，要先封闭球阀前的切断阀，翻开需要检修的球阀，完全开释阀体内部压力。假如是电动球阀或气动球阀，则应该首要断开电源和气源。
三、．一般软密封球阀均运用四氟（PTFE）作为密封材料，硬密封球阀密封面为金属堆焊而成。如需对管道球阀进行清洗，在拆开时需谨慎防止损坏密封圈而走漏。
四、法兰球阀拆装时，法兰上的螺栓螺母应先固定，然后将所有螺母稍紧，最后用劲固定好。如先将单个螺母强行固定好，再固定其他螺母，法兰面之间会因受里不匀导致垫面损坏或决裂，导致阀门法兰对接出介质走漏。
五、气动球阀提示假如对阀门进行清洗，运用的溶剂有必要和要清洗的配件不抵触，不腐蚀。假如是燃气专用球阀，则可用汽油进行清洗。其它零部件一般用中水清洗既可。清洗时，要完全的清洗洁净残留的尘埃，油污和其它附着物，如用清水无法清洗洁净，可在不损坏阀体和零部件的前提下，针对性的用酒精等清洗剂进行清洗。清洗完成后等清洗剂完全蒸腾后再进行装置。
六、假如在运用过程中发现填料处有纤细走漏，可以稍稍赶忙阀杆螺母，紧至走漏中止既可，不可继续拧紧。
七、长时间露天寄存，会导致阀门本体和部件锈蚀，无法正常运用。球阀寄存时应该防雨，防水，防潮，并将法兰盖盖紧。存储超越12个月的阀门，运用时应从头检验，以保证性能安稳。
How to protect and maintain pneumatic ball valves in order to extend their service life?
1、 Before use, water should be used to clean the pipeline and the overflow part of the valve body to prevent residual iron filings and other debris from entering the valve body cavity.
2、 When the ball valve is in a closed state, there is still some residual medium inside the valve body and it is also under certain pressure. Before repairing the ball valve, close the shut-off valve in front of the ball valve, open the ball valve that needs to be repaired, and completely release the internal pressure of the valve body. If it is an electric or pneumatic ball valve, the power and air sources should be disconnected first.
3、 Generally, soft sealed ball valves use tetrafluoroethylene (PTFE) as the sealing material, and the sealing surface of hard sealed ball valves is made of metal overlay welding. If it is necessary to clean the pipeline ball valve, care should be taken to prevent damage to the sealing ring and leakage during disassembly.
4、 When disassembling flange ball valves, the bolts and nuts on the flange should be fixed first, then all nuts should be slightly tightened, and finally firmly fixed. If a single nut is forcibly fixed first, and then other nuts are fixed, uneven pressure between the flange faces may cause damage or cracking of the gasket surface, leading to leakage of medium from the valve flange joint.
5、 Pneumatic ball valve prompts that if cleaning the valve, it is necessary to use a solvent that does not conflict with the parts to be cleaned and does not corrode. If it is a gas specific ball valve, gasoline can be used for cleaning. Other components are generally cleaned with medium water. When cleaning, it is necessary to completely clean residual dust, oil stains, and other attachments. If it is not possible to clean with clean water, targeted cleaning agents such as alcohol can be used without damaging the valve body and components. After cleaning, wait for the cleaning agent to fully evaporate before proceeding with the device.
6、 If fine leakage is found at the packing during use, the valve stem nut can be quickly tightened until the leakage stops, and cannot be further tightened.
7、 Long term outdoor storage can cause corrosion of the valve body and components, making it unable to function properly. When storing ball valves, they should be rainproof, waterproof, and moisture-proof, and the flange cover should be tightly covered. Valves stored for more than 12 months should be inspected from scratch during use to ensure stable performance.
