3.2 Additional connection for a
solenoid valve
An additional output for reduced air pres-
sure is required to allow the supply pressure
regulator to supply two pneumatic devices.
In some versions of Type 4708 (see sec-
tion 7 on accessories), a second output can
be made available by using an intermediate
plate.
Example: Pneumatic actuator with positioner
and pilot-operated solenoid valve
Þ
Supply
air must be supplied separately to the pilot
control.
The reduced supply pressure of the supply
pressure regulator is additionally routed to
the threaded connection at the side over the
corresponding holes in the intermediate
plate. All supply pressure regulators have
the same intermediate plate, except for
Type 4708-57xx, designed for attachment
to Type 3760 Positioner (Fig. 12), its inter-
mediate plate has a different hole assign-
ment for the air ducts.
All versions can be ordered made of alumi-
num or stainless steel and with either G or
NPT threads. See section 7 for more details.
