Vacuum valves are used in the food, beverage, pharmaceutical and chemical industries.
They are suitable for the protection of tanks and other closed systems against negative
pressure.
During installation, operation and maintenance please pay attention to the generally
accepted safety regulations as well as to the operating instructions.

Important notice !
•Valve/component suitable for vertical installation.
•Valve opens at a negative pressure of 3-5 mbar (30-50 mm WC).
Pressure compensation to ambient pressure by draw in air.
The valve will be closed by counter pressure of the weight.
•For higher temperatures (>40°C) use stainless steel (3) valve cone
(for DN 65).
•To avoid mistakes during assembly/disassembly, pay attention to the operating
instructions respectively the type plate

Execution with heating device:
•The heating insets may only be connected according to attached scheme. Pay
attention to the connecting voltage!
•Do not remove the heating inset from the flange during function test
(heating capacity). It may get damaged by overheating.

Execution with lifting device:
•Pneumatic lifting cylinder for function test and for lifting the valve cone
during CIP. The stroke of the lifting cylinder is factory preset.
So the stroke of the valve cone is limited to about 3 mm.
With too large stroke, the emerging splash amount increases.
•Suitable for treated compressed air, max. 6 bar
•Throttle of air inlet has to be adjusted upon setting into operation.
•Compressed air supply: air hose Ø 6/4.
