Functional Principle
When the pilot valve is activated, the angle valve is closed by
the pressure spring. The position indicator is invisible.
When the pilot valve is deactivated, the angle valve is
opened by the pneumatic actuator. The green position indi-
cator becomes visible.
The final positions can be polled by the electrical position
indicator.

Caution
Caution: dirt sensitive area
Touching the product or parts thereof with bare
hands increases the desorption rate.
Always wear clean, lint-free gloves and use
clean tools when working in this area.
Caution
Caution: vacuum component
Dirt and damages impair the function of the
vacuum component.
When handling vacuum components, take ap-
propriate measures to ensure cleanliness and
prevent damages.
Remove the protective lids and install the valve to the

Compressed Air Connection
DANGER
DANGER: moving parts
When the product is connected to the supply
media, parts can start moving. Moving parts can
catch parts of the body and cause injuries.
The connection to the compressed air supply
may only be established if
•the compressed air line is not pressurized
•the product is installed in a vacuum system or
•the moving parts are protected to avoid acci-
dental contact.
Specifications for the plastic tube.
•OD 6 mm
•resistance to pressure ≥10 bar overpressure
•material: PA soft or PU
To ensure leak tightness,
•cut the plastic tube orthogonally
•make sure the outside of the plastic tube is not
damaged.
The compressed air must meet the following specifi-
cations:
•purity classes 2 4 1 (ISO 8573-1)
•4 ... 8 bar overpressure
If using compressed air which contains oil, dispose
of it in accordance with the relevant regulations.
Compressed Air Inlet
Push the tube into the instant push-in fitting until the me-
chanical stop is reached. Check that it is correctly mounted
by slightly pulling.

Compressed Air Outlet
If necessary, unscrew the silencer and screw in the enclosed
instant push-in fitting (ø6 mm) for educting the compressed
air. Push the tube into the instant push-in fitting until the me-
chanical stop is reached. Check that it is correctly mounted
by slightly pulling.
For educting the compressed air,
unscrew the silencer from the

Electrical Connection
WARNING
WARNING: mains voltage
The pilot valve can get destroyed if a wrong
mains voltage is applied.
The local mains power rating must correspond
with the nominal voltage of the pilot valve (see
product nameplate). If they do not correspond,
exchange the pilot valve (→"Maintenance,
Repair").
Before connecting or disconnecting the product, turn
off the control system.
The cable must meet the following specifications:
•flexible
•conductor cross-section 0.75 mm2
•cable cross-section 10 mm
•7-pin with protective conductor
nSolder the cable. The polarity of the pilot valve
(solenoid coil) need not be taken into consideration.

DANGER
DANGER: compressed air
Physical injury can result if a pressurized com-
pressed air line is disconnected.
Before doing any work, turn off the compressed
air supply and relieve the compressed air lines.
DANGER
DANGER: moving parts
When the product is disconnected from the
supply media, parts can start moving. Moving
parts can catch parts of the body and cause
injuries.
The product may only be disconnected from the
compressed air if
•the product is installed in a vacuum system or
•the moving parts are protected to avoid acci-
dental contact.
