Compressed air tubing and fittings
Use only straight fittings. If elbow connectors cannot be avoided, use plug connectors from the
Quick Star series.
Select compressed air tubing and fittings of the required size as specified in section 3.4.1.
Arrange the tubing between the valve (VPWP) and the drive as follows:
–
symmetrical
–
as short as possible
A tube length of 60 % of the cylinder stroke length is optimal.
Max. tubing length = cylinder stroke length
Use only clean compressed air tubing and fittings.
Do not use flow control valves or check valves in the air supply lines.
Do not let the tubing project into the travel range.
To minimise the effects of bending forces on the positioning behaviour:
Select a sufficiently large energy chain.
