The advantages of pneumatic ball valve

pneumatic ball valve of pneumatic ball valve with pneumatic actuator, pneumatic ball valve usually configure various accessories, such as electromagnetic air valve, air source treatment sanlian pieces, limit switch, locator, control box, etc. , in order to realize the local control and remote centralized control, pneumatic valve in the control room can control the switch, do not need to run to the field or high altitude and dangerous manual control, to a great extent, save the human resources and time and safety.
pneumatic ball valve is on the basis of manual stainless steel flanged ball pneumatic valve with pneumatic actuator. When air through the pneumatic actuator, pneumatic valve actuator drives in open and close action. Control effect is good, sealed performance is strong, has been widely used in all kinds of corrosive conditions.
pneumatic ball valve is mainly used to cut or connect line in the medium, can also be used for flow regulation and control, it compared with other types of pneumatic valve has the following several advantages.
, fluid resistance small, pneumatic ball valve is for all pneumatic valve minimum fluid resistance among the class a, even reducing pneumatic ball valve, the fluid resistance is small.
, thrust bearings reduce pneumatic valve stem 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.
and pneumatic valve stem seal 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.
