PED CATEGORIES AND FLUID GROUP
The FL series regulators without built-in safety slam-shut 
devices (FL and MFL) may be used as a stand-alone safety 
accessory in a fail-to-close conguration to protect pressure 
equipment under the Pressure Equipment Directive 97/23/
EC categories.
The technical features of the downstream equipment, 
protected by this regulator, should be classied under 
a higher category according to the Pressure Equipment 
Directive 97/23/EC.
According to EN 14382, only in an integral strength and 
Class A type conguration (in both over and under pressure 
protection congurations), can the possible built-in safety 
slam-shut device (BFL) be classied as a safety accessory 
according to P.E.D.
The minimum PS between slam-shut device and pilot shall 
be the PS of the safety accessory, complying to EN 14382 
for integral strength types.
The technical features of the downstream equipment, 
protected by possible built-in safety slam-shut device 
(conguration BFL Class A and integral strength) shall be 
classied according to the Pressure Equipment Directive 
97/23/EC, see table 1.

The built-in pressure accessories (e.g. pilots OS/80X, 
OS/80X-PN, PRX/, PS/, and V/31-1 series or lters  
Type SA/2, FU/ and FD-GPL/) conform to Pressure 
Equipment Directive (P.E.D.) 97/23/EC Article 3 Section 
3 were designed and manufactured in accordance to the 
Sound Engineering Practice (S.E.P.).
According to Article 3 Section 3, these “S.E.P.” products 
must not bear the CE marking.
