ADVANTAGES●● Twofold safety: The combination

of a working diaphragm and an additional safety diaphragm prevents gas from escaping in the event of a fracture (.12)

●● The robust design will hold up to challenging operating conditions

●● High pressure up to 7 bar rel./101.5 psig

●● High level of gas tightnessFollowing leakage rates are available:.9 ≙ to < 6 x 10-3 mbar l/sSP.13 ≙ < 6 x 10-6 mbar l/sST.13 ≙ < 1 x 10-5 mbar l/sSP.12 ≙ < 6 x 10-6 mbar l/s

POSSIBLE AREAS OF USE●● Energy technology – especially

in nuclear facilities

●● Chemical industry

●● Process industry

●● Research and development

The performance values for the series models shown on this data sheet were determined under test conditions. The actual performance values may differ and depend in particular on the usage conditions and therefore on the specific application, on the parameters of the components involved in the user’s system and on any technical modifi- cations carried out which deviate from the standard configuration or the as delivered condition.

If individual designs have been created for specific customers on the basis of series models, other technical performance data may apply. Before operation begins, the relevant operating instructions and/or assembly or installation instructions should be read and the safety information contained in these instructions should be noted. KNF reserves the right to make changes to the product and the associated documen-tation without prior notice to the customer.
