How to identify safety mini rev type with qi type pneumatic valve

what is tiny qi type safety pneumatic valve refers to the opening height of the pneumatic valve is trace, does not allow suddenly turned on or off 'water hammer' phenomenon, is mainly used in liquid medium. He is typical of the import and export diameter is the same.
what is the rev type safety pneumatic valve when rise to pneumatic valve core and pneumatic seat ring size of pneumatic valve seat diameter area ( Increase the height of the x aerodynamic circumference of the sealing face of valve core area = pneumatic sealing face of valve core area, is all opened; Its typical characteristics is exports diameter greater than imports.
a, all rev type pneumatic valve and raise safety security the main difference between the pneumatic valve is different, the height of the opening in the general safety mini rev type pneumatic valve opening height of the pneumatic valve seat throat diameter / ~ /, and all rev type pneumatic valve opening is safety for the pneumatic valve seat throat diameter/above.
2, selection considerations: emissions, safety of pneumatic valve must be greater than a container of safety discharge capacity; B, absolutely smooth operation pressure of containers, should consider to choose safety mini rev type pneumatic valve ( Such as compressor cylinder; C, high pressure vessel, large containers, and in large volumes of water safety, low pressure container, had better choose all rev type pneumatic valve (safety Equipment such as the reaction kettle.
3, the safety of pneumatic valve opening is to point to: pneumatic disc leave the actual lift in the closed position.

safety mini rev type with qi type pneumatic valve
what is the difference between micro and pneumatic valve type safety refers to the safety of the pneumatic valve opening height is trace, suddenly are not allowed to open or close the 'water hammer' phenomenon, is mainly used in liquid medium; He is typical of the import and export diameter is the same.
what is the rev type safety pneumatic valve when rise to pneumatic valve core and pneumatic seat ring size of pneumatic valve seat diameter area ( Increase the height of the x aerodynamic circumference of the sealing face of valve core area = pneumatic sealing face of valve core area, is all opened; Its typical characteristics is exports diameter greater than imports.
a, all rev type pneumatic valve and raise safety security the main difference between the pneumatic valve is different, the height of the opening in the general safety mini rev type pneumatic valve opening height of the pneumatic valve seat throat diameter / ~ /, and all rev type pneumatic valve opening is safety for the pneumatic valve seat throat diameter/above.
