3.2.4 Proportional directional control valve type MPYE−...
· Fit the proportional directional control valve as close as
possible to the drive. Short compressed air tubing will
ensure the dynamics of the system.
· If the proportional directional control valve is to be used
in an environment subjected to heavy electrical interferĆ
ence, it should be insulated from the mounting surface.
· Fitting onto moving parts
If fitted to moving parts, the proportional directional conĆ
trol valve must be mounted at right−angles to the direcĆ
tion of movement. Acceleration forces then have no influĆ
ence on the valve slide setting.

· Use silencers with a large rated flow (e.g. U−1/8).
Reducing loud exhaust noises:
· Install larger silencers with the aid of tubing or pass the
ducted exhaust into a small compressed air reservoir and
exhaust this with a large silencer. Make sure that the
screw connectors and tubing provide sufficient flow. Keep
the tubing as short as possible.
