Four PZ673X pneumatic plug-in valve valve optional drive device model configuration table:

Optional accessories for pneumatic actuators:

1. Single or double control solenoid valve (24V, 220V and other voltages are available for selection, if necessary, an explosion-proof solenoid valve can be selected).

2. Proximity switch.

3. Air source treatment triples (including pressure reducing valve, filter, lubricator).

4. Electric/pneumatic valve positioner (for adjustment type).

1. The cylinder is a device that uses compressed air as a medium to convert its energy into mechanical energy to realize linear motion. It is an executive component widely used in various pneumatic systems and a basic component for industrial automation.

4. Precautions for the correct use of the cylinder:

(1) The movement direction of the load must be consistent with the movement direction of the piston rod to prevent the piston rod from being twisted.

(2) Use the combination of filter, pressure reducer and lubricator (F-R-E combination) to adjust the air quality and increase the service life.

(3) Select a cylinder with a larger output than the actual load to avoid danger when the air pressure is insufficient.

(4) Pay attention to the operating environment temperature. The operating temperature of the piston ring and sealing material in the cylinder is generally limited to within -5℃—+60℃.

(5) In a corrosive gas environment, the material of the piston and sealing part in the cylinder is generally PTFE.
