2.4.2 Mounting the valve in the system
When installing the valve make sure it is not unevenly loaded
by external forces or vibrations.
During operation or testing the inlet / outlet and vent hole
connections must not be open or unprotected
- If it is a blowing seal, the conveying pipe line to be connected to the blowing
seal should ideally have the same diameter as the connections on the seal.
- If there is some difference between the inner diameters of the blowing channel
and the conveying line, the transition from one diameter to the other should be
as smooth as possible.
- If the valve is fitted with air vents, the area of the venting pipe should be equal
to the total area of both vent connections.
Remove all packing material and preservatives.
Check for any transport damages.
