peD Conformity Statement and Information
The CSB700 Product Series is in conformity with the
Pressure Equipment Directive PED 2014/68/EU. Pressure
regulator does not require any supplementary upstream
safety accessory for protection against overpressure
compared with its design pressure PS, when upstream
reducing station is sized for a max downstream incidental
MIPd <= 1 .1 PS .
