1) For air with molecular flow.
2) Pressure difference Δp = 0, and compressed air = 6 bar (overpressure).
3) Cycles under clean operating conditions and with recommended mounting orientation.
If the valve is operated under harsh or dirty conditions, it should be cleaned / maintained
before the specified service time to maintenance has been reached.
4) Compressed air = 4 bar (overpressure).
5) Recommended mounting orientation: valve seat toward vacuum chamber.

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 of clamps which are suited to overpressure.
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 valve to the vacuum system by means of
the clamp flange fittings.

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.
DANGER
DANGER: movement of the valve plate
When the valve is in operation, the valve plate can catch parts of the
body and thus cause injuries.
Take appropriate measures (e.g. protective grid) to prevent access to
the inside of the installed valve.
The plastic tube must meet the following specifications:
•OD 6 mm
•bursting pressure ≥10 bar overpressure
•material: PA soft or PU
To ensure leak tightness of the instant push-in fitting
•cut the plastic tube perpendicularly
•make sure the outside of the plastic tube is not damaged
The compressed air must meet the following specifications:
•purity classes 2 4 1 (ISO 8573-1)
•4 … 8 bar overpressure
