11th April 2016: Tekno valves is pleased to announce certification of SWN-12/45, soft seated valves in O-ring seal design with a 45 mm diameter aluminum hand wheel. The design meets industry standards in performance, flow and resistance to ignition in Oxygen at working pressure of 300 bar (Test pressure 360 bar).
The design is intended for technical and medical cylinders having water capacity less than 10 litres, generally with 17E / M18x1.5 and equivalent neck threads. The valve aesthetically matches with the light-weight cylinder offering cost benefit to the customers
The design is also available with an optional inline Residual pressure device (RPD), Series IWN-12/45, to prevent ingress of contamination by maintaining positive pressure in the cylinder. The RPD also incorporates a non-return function to prevent back flow of fluids into the cylinder from a higher pressure source.
