P.E.D. Categories
This product may be used as a pressure accessory with
pressure equipment in the following Pressure Equipment
Directive. For information on the current PED revision see
Bulletin: D103053X012. 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 maximum
downstream incidental MIPd <= 1.1 PS.
