3.2.5 Compressed air tubing and screw connectors
· If possible, use screw connectors from the QS or QSM
series. In the case of drives with 3/8" connection,
CKĂscrew connectors of type CK−3/8−PK−13 are also
permitted.
· Use only straight screw connectors. If angled connectors
cannot be avoided, use plug connectors from the Festo
Quick Star series.
· Use screw connectors with the largest possible rated
width. If the proportional directional control valve and the
drive have connections of different sizes, select the
largest possible rated width of the smaller connection
size.
· Depending on the screw connectors, always use the
largest possible tubing diameter.
· Avoid installing restrictors or non−return valves in the
supply line.
· Arrange the tubing so that it does not project into the
positioning range.
· Use only clean compressed air tubing and connectors.
· Use tubing as short as possible between the valve
(MPYE−5−...) and the drive and arrange the tubing
symmetrically.
The permitted tubing lengths for the relevant drive can be
found in appendix A.
Details on permitted temperature and pressure ranges for
tubing and connectors can be found in the Pneumatics
Catalogue.
