A common type and the matters needing attention of the reversing pneumatic valve

the selection of pneumatic directional control pneumatic valve pneumatic reversing pneumatic valve is the control component in the pneumatic system, is used to control the flow of fluid in the system, its style type many, the user can choose according to their own needs.
the reversing common types of pneumatic valve has the following several kinds:
in the outlet points: two-way, tee, four-way, and five; According to the work location points: two and three.
the control points: pneumatic and electric control, direct acting and pilot operated; Points:
the accused medium fluid pneumatic valve, pneumatic valve and gas
according to the feature points: normally closed, normally open, the seal and drainage and gas; According to the structure points:
stop pneumatic valve and pneumatic valve;
pneumatic reversing pneumatic valve when the choose and buy, should pay attention to the following:
, the reversing of the pneumatic valve thread interface: the reversing of the pneumatic valve nominal diameter is not one-to-one correspondence with the port thread, therefore, should be paid attention to when choosing the reversing pneumatic valve interface thread.
, the installation of the reversing pneumatic valve size: same model, the function of the reversing pneumatic valve manufacturer for different sizes of its appearance and installation is not the same.
, directional movement is flat and agile, don't leave
pneumatic valve, electromagnetic especially ac solenoid pneumatic valve should be paid attention to its insulation performance. To ensure the personal safety of operators.
, reversing pneumatic valve should be no external leaks, internal leakage as small as possible. Otherwise, will affect the normal work of the system, and waste of energy.
and pay attention to the date of pneumatic valve, reversing pneumatic valve put too long, aging of the lubricating oil and the influence the reversing the normal work of the pneumatic valve.
