Use only straight fittings. If elbow connectors cannot be
·
avoided, use push−in fittings from the Quick Star series.
Size the tubing and tubing connectors as specified in sec
·
tion 2.4.1.
Arrange the tubing between the valve (VPWP) and the
·
drive symmetrically.
Use only clean tubing and fittings.
·
Do not use flow control valves or non−return valves in the
·
supply lines.
Arrange the tubing so that it does not project into the
·
positioning range.
For good positioning behaviour during operation, pressure
fluctuations of max. 1 bar are permissible in front of the pro
portional directional control valve. In order to check the sta
bility of the supply pressure, you can fit a pressure measur
ing point directly in front of the proportional directional
control valve.
If necessary, select a sufficiently large energy chain in order
to minimise the effects of bending forces on the positioning
behaviour.
