During mounting, the user should select the tightening torque, taking into account the following data:
•
Relevant process connection
•
Material pairing between process connection and container material
•
Lubrication (for hygienic variants, e.g. NSF H1 or FDA 21 CFR 178.3570)
•
Seal
•
Environmental influences (e.g. pressure, temperature)
The technical regulation VDI 2230 provides assistance here.
Typically, the tightening torque is 5 to 10 Nm. If ordered from the accessories, the tightening torque is
10 Nm for the supplied welding sockets.
The sealing surfaces between the tank, container, or pipe and the device must be clean and free from
mechanical damage.
With process connection G 1/2", the device is sealed elastomer-free, without an additional seal in the
area of the device tip. If sealing is not provided via the PEEK tip, sealing tape (e.g. PTFE) in the area of
the thread is recommended.
The sealing effect of the device tip is optimum at first mounting. Mounting for test purposes is not nec-
essary.
NOTICE!
Damage to the device tip due to improper handling.
The device tip may be damaged during mounting or re-installation.
Check the device tip for notches or grooves.
Only use the hexagon wrench for screwing in.
