Technicaldata
Two versions of the S020 in DN15 and DN20 exist, having different K factors.
Only version 2, identified by the "v2" marking, is available from March 2012. The "v2" marking can be found:
• on the bottom of the DN15 fitting in plastic:
• on the side of the DN15 or DN20 fitting in metal:
The names of the following norms have changed in the Operating Instructions:
• for the welding ends, norm BS 4825 is renamed BS 4825-1.
• for the clamp connections, norm BS 4825 is renamed BS 4825-3.
• The norm for the clamp connections, ISO (for pipes acc. to EN ISO 1127 / ISO 4200), has been replaced by norm DIN 32676
series B (for pipes acc. to ISO 1127 / ISO 4200 / DIN 11866 series B).
• The norm for the clamp connections, DIN 32676 series A (for pipes acc. to DIN 11850) has been added.
