The part number (No) can be taken from the product nameplate.
If not indicated otherwise in the legends, the illustrations in this document corre-
spond to the valve with the nominal diameter DN 25 ISO-KF. They apply to valves
with other nominal diameters by analogy.
We reserve the right to make technical changes without prior notice.
If not indicated otherwise, the dimensions are given in mm.
The Angle valves are used as shut-off or venting devices for vacuum applications.
When compressed air is admitted to the Angle valve, it opens.
When the compressed air pressure drops, the Angle valve is closed by a pressure
spring.

Caution: overpressure
Obstructing the bore hole can cause injuries by catapulted parts (e.g.
cover).
Make sure the bore hole is not obstructed.

For easy adaptation to the space requirements, the actuator is infinitely rotatable.
Press the actuator down and remove the hexagon socket set screws.
When the actuator is released, the pressure spring is partly
relieved, which causes the upper part of the actuator to rise by a
few millimeters.

DANGER
Caution: overpressure in the vacuum system >1 bar
Injury caused by released parts and harm caused by escaping process
gases can result if clamps are opened while the vacuum system is
pressurized.
Do not open any clamps while the vacuum system is pressurized. Use
the type of clamps which are suited to overpressure.
DANGER
Caution: overpressure in the vacuum system >2.5 bar
KF flange connections with elastomer seals (e.g. O-rings) cannot
withstand such pressures. Process media can thus leak and possibly
damage your health.
Use O-rings provided with an outer centering ring.
Caution
Caution: vacuum component
Dirt and damages impair the function of the vacuum component.
When handling vacuum components, take appropriate measures to
ensure cleanliness and prevent damages.
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.
Remove the protective lids and install the product.
Any mounting orientation and flow direction may be chosen.
