Pneumatic ball valve and other advantages of pneumatic valve analogy

pneumatic ball valve is mainly used to cut or connect line in the medium, can also be used for flow regulation and control, the advantages of it compared with other types of pneumatic valve, pneumatic valve, fluid resistance small, ball will be all pneumatic valve minimum fluid resistance among the class a, even reducing pneumatic ball valve, the fluid resistance is small. , thrust bearing, reduce the pneumatic valve rod friction torque, can make the pneumatic valve stem long smooth and flexible operation. , pneumatic valve seat sealing performance is good, use the sealing ring made of elastic material, such as teflon structure is easy to be sealed, and pneumatic ball valve pneumatic valve sealing ability increases as the medium pressure increases. , pneumatic valve rod sealing is reliable, the pneumatic valve stem will only be used as the rotation without lifting movement, pneumatic valve stem packing seal is not easy to damage, and sealing ability increases as the medium pressure increases. , such as ptfe material has good self-lubrication, with ball friction loss is small, so the pneumatic ball valve of long service life.
, bottoms type pneumatic valve stem and pneumatic valve stem head convex order to prevent the pneumatic valve rod, such as pneumatic stem seal damage caused by fire, convex order can also be formed between the pneumatic valve body and the metal contact, to ensure that the pneumatic valve stem seal.
, anti-static function: in a sphere, pneumatic valve, pneumatic valve body between the spring, will be generated switching process of electrostatic export, actuators.
