Î
Before installation, depressurize the
relevant plant section.
Any mounting position may be used. The fol-
lowing applies concerning the installation:
Î
Mount the solenoid valve in such a way
that the M16x1.5 cable gland faces

possible, mount it in the horizontal posi-
tion).

0.32 can
be fitted with a restrictor plate to adjust the
actuating time of the pneumatic actuator (see
section 3.1).
The restrictor plate is mounted on rotary ac-
tuators with a NAMUR interface according
to VDI/VDE 3845, on an adapter plate for
linear actuators with NAMUR rib according
to IEC 60534-6-1 or on a connection block
for the Type 3277 Pneumatic Actuator.
Î
Fasten the restrictor plate using two slot-
ted-head screws (1) and washers (2).
Make sure that the O-rings (4, 5 and 6)
are seated properly.
