4 601255EB (2014-01)

Intended Use

The angle valves are used as shut-off and venting devices for

vacuum applications.

Functional Principle

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.

3.2 Vacuum Connection

DANGER

DANGER: 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 clamps which are

suited to overpressure.

601255EB (2014-01) 15

DANGER

DANGER: 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 vac-

uum component.

When handling vacuum components, take appro-

priate 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.

3.3 Compressed Air Connection

p

DANGER

DANGER: compressed air

Unprofessionally handling compressed air can

cause physical injury.

Adhere to the relevant regulations and take the

necessary precautions when handling compressed

air.

Instant push-in fitting

The standard product is equipped with an instant push-in fitting

for a plastic tube ø4 mm or ø¼".

If you are using another plastic tube (e.g. ø6 mm), exchange the

instant push-in fitting.

AF 2.5

Compressed air inlet

601255EB (2014-01) 19

Plastic tube

DANGER

DANGER: moving parts

When the product is connected to the supply me-

dia, 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 acciden-

tal contact.

Specifications for the plastic tube:

bursting pressure 10 bar overpressure

material: PA soft or PU

20 601255EB (2014-01)

To ensure leak tightness:

cut the plastic tube orthogonally

make sure the outside of the plastic tube is not

damaged

Push the plastic tubes into the instant push-in fittings until the

stop position is reached and check for correct mounting by

slightly pulling.
