Malfunction due to dirt blocking the quick
exhaust valve.
No substances must be allowed to enter the
device during mounting, transport or stor-
age.
5.1 Mounting position
Risk of damage to the quick exhaust valve
due to incorrect mounting position.
Do not mount the quick exhaust valve with
the exhaust port facing upward.
Î
Mount the quick exhaust valve with the
exhaust port (EXH) facing downward or
to the side.
Î
If the quick exhaust valve can become
covered in snow, iced up or dirt can
collect in the device, it must be mounted
with the exhaust side facing downward
or protected by a suitable fixture/cover.
5.2 Attachment and hook-up
Risk of damage to the quick exhaust valve
due to it being combined with a volume
booster.
Do connect the quick exhaust valve in combi-
nation with a volume booster.
Risk of damage or malfunction of the quick
exhaust valve due to lack of protection
against dirt, icing up or snow.
In versions with silencers, take suitable pre-
cautions to protect it against dirt, icing up
and/or snow.
Follow the instructions below during mount-
ing:
Î
To vent the actuator as quickly as possi-
ble, the quick exhaust valve must be
mounted as close to the pneumatic actu-
ator as possible.
Î
Mount the quick exhaust valve between
the positioner or solenoid valve and the
pneumatic actuator (see Fig. 2).
Î
Mount the quick exhaust valve in such a
way that the compressed air flows
through the valve in the direction indicat-
ed by the arrows shown in Fig. 2.
Î
Hook-up with a volume booster is not
permissible.
Î
Select piping and screw fittings with the
largest possible flow rate.
