Caution!
Damage to seals and threads
Stainless steel threads tend to seize and cold weld and must be greased.
Damage to seals and threads can result in malfunction.
► Ensure that an adequate film of lubricant is applied. No grease residues
must be visible once the valve has been assembled completely.
► For product contact seals only use suitable greases and oils.
► Observe the safety data sheets issued by the lubricant manufacturer!
Carry out the following steps:
1.
Apply a light film of lubricant to all threads.
2.
Grease all seals – including the O-rings at the top and bottom of the actuator
piston stem – very thinly.
!
Do not grease V-rings

Hint!
GEA Tuchenhagen recommends Rivolta F.L.G. MD-2 and PARALIQ
GTE 703. These lubricants are approved for foodstuff and are resistant
to beer froth. They have the NSF-H1 (USDA H1) registration. They do
not affect the taste or the consistency of the products and are
compatible with the seals in contact with product.
Rivolta F.L.G. MD-2 can be ordered from GEA Tuchenhagen. Using
other types of grease can result in malfunctions or in premature seal
failure. The warranty will also become null and void.
A Manufacturer's Declaration for these products can be obtained from
GEA Tuchenhagen if required.
A thin film of grease is required on the seals to ensure the proper
function of the fittings. It reduces friction and extends the service life
of the seals. This is absolutely harmless from a health and hygienic
point of view.
Running dry must be avoided!
