Surface finish
Inside areas in contact with
product
Surface roughness R
a
≤ 0.8 µm (standard)
Outer surfaces Metal blank fine turned and/or polished
Inside areas (with the exception of the metal bellows) in contact with product can be
electropolished/passivated or ground on request. These methods will bring up surface roughness
to R
a
≤ 0.6 µm / 0.4 µm.
Resistance of sealing materials
Product contact seals
The resistance of sealing materials depends on the type and
temperature of the medium conveyed. The exposure time can
adversely affect the service life of the seals. The sealing
materials comply with the regulations of FDA 21 CFR 177.2600
or FDA 21 CFR 177.1550.
