General information
Acceptance
Due to their use together with nitrogen, all components are de-
signed according to DGR 2014/68/EU / ASME Sec. VIII Div. I. di-
rectives. As such, they have passed all mandatory tests, have been
certified, and carry the component tags that are required for their
proper use. Basically, all pressure-bearing equipment is subject to
an inspection according to DGR 2014/68/EU. At nominal sizes ≤
DN32, according to DGR 2014/68/EU (article 4, paragraph 3), no
CE mark is required. Components that are subject to inspection
according to the ASME directive, are not marked if the nominal
value amounts to <6 inch. Safety-related equipment, such as safe-
ty valves, always carry the CE mark due to their safety-relevant
function, or, in case of the ASME-inspection, the UV-stamp.
Standard connections
With regard to their connections, all Roth Hydraulics gas compo-
nents comply with the following standard norms:
> Threaded pins DIN 3853 / ISO 8434
> Screw-in borings DIN 3861 bore shape W
> SAE flange ports ISO 6162 (SAE J518)
> Square flange connections ISO 6164
(other connections can be added upon request)
Surfaces
The surfaces of the individual components are normally galva-
nized or chromated. For possible variations see description of
components.
