The part number can be taken from the product nameplate.

If not indicated otherwise in the legends, the illustrations in this document cor-

respond to the valve with the vacuum connection DN 25 ISO–KF. They apply to

valves with other vacuum connections by analogy.

We reserve the right to make technical changes without prior notice.

All dimensions are indicated in mm.

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

applications.

4 Installation

Skilled personnel

The vacuum connection may only be established by persons who

have suitable technical training and the necessary experience or who

have been instructed by the end-user of the product.

DANGER

Caution: overpressure in the vacuum system >1bar

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.

Caution

Caution: dirt sensitive area

Touching the product or parts thereof with one's 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 appropriate measures to

ensure cleanliness and prevent damages.

Keep the lids.

Skilled personnel

The compressed air connection may only be established by persons

who have suitable technical training and the necessary experience or

who have been instructed by the end-user of the product.

Caution

Specifications for the compressed air:

•=free of particles >5 µm

•=3 ... 7 bar overpressure

•=dry, free of oil or containing oil (Keep using the same quality).

If using compressed air which contains oil, dispose of it in accordance

with the relevant regulations.

Caution

The plastic tube must meet the following specifications:

•=bursting pressure ≥10 bar overpressure

•=material: PA soft or PU.

Caution

To ensure leak tightness of the instant push-in fitting

•=cut the plastic tube square

•=make sure the outside of the plastic tube is not damaged.

Caution: plastic thread

The plastic thread is damaged by tilting or overturning the instant

push-in fitting.

•=use the enclosed instant push-in fitting (with extra-long thread)

only.

•=screw in the instant push-in fitting without tilting it and without

exceeding the tightening torque of 0.5 Nm.

For connection of a ø6 mm plastic tube, exchange the instant push-in fitting.
