The advantages of pneumatic valve

Pneumatic 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 valve:, small fluid resistance, valve is all valve class a kind of fluid resistance small, even if the reducing valve, the fluid resistance is small. Friction torque, thrust bearing, reduce the stem, can make the 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 easy to seal, and valve sealing ability increases as the medium pressure increases. , pneumatic valve rod sealing is reliable, the valve stem will only be used as the rotation without lifting movement, the 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 body friction loss is small, the long service life of the valve. , bottoms valve stem and valve stem head convex order to prevent the valve stem, stem seal damage caused by such as fire, convex order between the body and also can form metal contact, to ensure that the valve stem seal. Anti-static function, pneumatic valve: in the body, the valve stem and valve body between spring, will be generated switching process of electrostatic export, actuators.
