Pressure regulator plates
P−pressure regulator
(identifier R1−...−6 and
R1−...−10) Mode of operation:
The P−pressure regulator regulates the pressure in front of
the valve in channel 1 (P). In this way channels 2 and 4 have
the same regulated pressure. During the exhaust procedure
the valve is exhausted from channel 2 to channel 3 and from
channel 4 to channel 5.
The advantages of this pressure regulator are:
The pressure regulator is not affected by the exhaust
procedure because regulation takes place upstream of
the valve.
The pressure regulator can always be set, because the
pressure from het valve terminal is always present.
Application example:
An equally high working pressure is required at work
connections 2 and 4.
A lower working pressure (e.g. 3 bar) is required than
the operating pressure present at the valve terminal
(e.g. 8 bar).
