Tekno Valves is pleased to offer wheel operated Acetylene cylinder valves in O-ring seal design for “B” and “MC” style small cylinders 

in series BSWN-12/D-30 and BAWN-12/D-30 respectively.

All series meets special tests for acetylene service as per EN ISO 10297:2017 which ensures resistance to acetylene detonation in case soft seat is fully burnt by subsequent metal to metal sealing. The design, hydraulically tested at 909 bar, offers significant benefits over traditional metal seated single spindle packed design valves by providing reliable external and internal tightness, low torque operation, high cycle life and safe failure under excessive torque.

Valves are tested and certified to EN ISO 10297:2017 for maximum test pressure of 60 bar by BAM Berlin. Valves without integrated fuse alloy are available with “Pi” mark in accordance with European Transportable Pressure Equipment Directive (TPED), 2010/35/EU
