Other materials in accordance with the valve specification.
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
All sealing materials in the product contact area are suitable for
applications in the food industry. The durability of the sealing
materials depends on the type, temperature and contact time of
the conveyed media. The final assessment of the suitability of
the material is therefore the sole responsibility of the plant
operator, even if the materials meet all common guidelines of
the food industry (for further information see material
certificates).
