Warning!
risk of injury from discharge of medium and release of
pressure.
▶ Tighten the body screws sufficiently (see "Tab. 3").
→
Move the actuator to the lower actuator position (CFA, NC: by
removing pilot pressure; CFB, NO: by applying the pilot pressure).
→
Without applying pilot pressure, tighten the body screws to the
permitted tightening torque (see "Tab. 3").

Danger!
risk of injury from high pressure in the system.
▶ Before disconnecting lines and valves, turn off the pressure and
vent the lines.
Warning!
risk of injury from unsuitable connection hoses.
Hoses which cannot withstand the pressure and temperature
range may result in hazardous situations.
▶ Use only hoses which are authorized for the indicated pressure
and temperature range.
▶ Observe the data sheet specifications from the hose manufacturers.
8.4.1. connection of the pilot medium
To comply with the degree of protection IP65 / IP67 on the
pilot air port which is not required (for CFA, NC and CFB,
NO), install an exhaust air line in the dry area.
For the assignment of pilot air ports refer to the installation and dimen-
sional drawing included with delivery of the valve. Compare also the
information given in chapter "6. Structure and function".
The use of pneumatic hose with a minimum size of 6/4 is recommended.
For longer hose lengths the hose cross-sections should be adapted
accordingly.
In aggressive surroundings and in situations where moisture
could enter the actuator via the exhaust air port or muffler
the exhaust air should be collected and ducted to a non-
critical location.
