Chemical Resistance Chart 7150.2/2-10 BOA®-H Maintenance-free globe valves with metal-to-metal seat and bellows seal Grey cast iron PN 16 DN 15-300 Nodular cast iron PN 16 DN 15-350 Nodular cast iron PN 25 DN 15-150 The details given in this chemical resistance chart are based on experimental values, Dechema lists (by the German society for chemical apparatus) and information provided by the manufacturers. The corrosive load is strongly influenced by the operating conditions, temperatures and concentrations. The hydroabrasive wear and tear of suspended fluids has not been taken into consideration. Thus the details in this list are only for orientation and are not guaranteed. Temperature limits: PN 16, GJL-250 --10 °C to +300 °C, GJS-400-18-LT --10 °C to +350 °C, PN 25, GJS-400-18-LT --10 °C to +350 °C, Chemical resistance chart see overleaf
