PED Conformity Statement and Information
The CSB400 Product Series is in conformity with
the Pressure Equipment Directive PED 97/23/EC.
The exceptions to this previous statement are
the Types CSB403 and CSB423. Both of these
Types are not yet certified to conform with the
PED Directive.
Pressure regulator does not require any
supplementary upstream safety accessory for
protection against overpressure compared with
its design pressure PS, when upstream reducing
