Compressed air tubing and screw connectors ( 4 )
S Use only straight screw connectors. If angled connectors
cannot be avoided, use plug connectors from the Quick
Star series.
S Cut compressed air tubing and hoses to the required size,
as specified in the manual for the drive used.
S Arrange the tubing between the valve (MPYE-5-...) and the
drive symmetrically.
S Use only clean compressed air tubing and connectors.
Details on permitted temperatures and pressure ranges
for tubing and connectors can be found in the products
catalogue.
S Do not install restrictors in the supply lines.
S Arrange the tubing so that it does not project into the
positioning range.
For good positioning behaviour during operation, fluctuations
in pressure of max. 1 bar are permitted in front of the propor-
tional directional control valve. In order to check the stability
of the supply pressure, you can fit a pressure measuring
point directly in front of the proportional directional control
valve.
