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.
