2.6.5 Tubing and fittings
· 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 secĆ
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 proĆ
portional directional control valve. In order to check the staĆ
bility of the supply pressure, you can fit a pressure measurĆ
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.
