What's the difference between a pneumatic valve valve with other classes?

Compared with other types of valve pneumatic valve has the following advantages: anti-static function: in the body, the valve stem and valve body between spring, static export will be generated switching process. Enforcement agencies; Stem seal is reliable, due to 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; 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; Thrust bearings reduce stem friction torque, can make the valve stem long smooth and flexible operation; Because the materials such as ptfe has good self-lubrication, with body friction loss is small, the long service life of the valve. Bottoms type 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 stem seal; Pneumatic valve fluid resistance small, the valve is the smallest of all valve fluid resistance in class a, even if the reducing valve, the fluid resistance is small. Pneumatic valve is mainly used to cut or connect line in the medium, can also be used for flow regulation and control, in the above several aspects with the same valve type, by contrast, the rotation of the advantage of stainless steel pneumatic valve way stainless steel pneumatic valve is a valve with pneumatic actuator. Pneumatic actuators to perform relatively fast speed, and does not require hands-on workers, to a great extent, save the human resources and time. Stainless steel valve pneumatic valve is made. The rotation of the pneumatic valve with the same degree of action, different is the cock body is a body, has a circular hole or channel through its axis. Surface and opening ratio should be such, that when the rotation at the inlet and outlet shall all be present surface, thereby cutting flow.
