Single-piece disc/stem unit optionally fluoroplastic• lined with pure PFA for maximum corrosion resistanceand a long service life.Very low friction values and torquesduring opening and closing due to thecombination of a PFA disc/stem unit with a PTFE body • optionally antistatic PFA-L • disc/stem core made of highly torsion-resistant Duplex stainless steel 1.4517/CD4MCU (DN 450-1000/18“-40“: SS 1.4435/316L)Alternatively metallic• made of precision cast stainless steel - polished sealing surfaces, thereforevery low friction values- polished disc surfaces on request • other materials on request, e.g. Hastelloy® C, titanium? Thick-walled PTFE and TFM-PTFE lining of the valve body • TFM-PTFE lining (DN 50-400/2“-16“with PFA-lined disc: PTFE as standard, optionally TFM-PTFE)• Lining thickness 3-3.5 mm (0.12-0.15“)• High permeation resistance • Vacuum-proof • Optionally antistatic PTFE-L, PE-UHMWWide sealing surfaces of body lining for reliable sealing even with mating flanges with large radii, e.g. glass-linedcomponents ? Permanently elastic seal in the valveopening by means of silicone insertunder the PTFE body lining.• Optionally FKM insert (e.g. Viton®) for usewith chlorine gas for example 231376824 5? Double-action, maintenance-free and self-adjusting top andbottom stem sealing,therefore reliable even with manyswitching cycles and fluctuatingtemperatures:- primary: body lining againstdisc/stem shoulder- secondary: O-ring FKM, optionally FFKMCompliant with the German Clean Air Act even in the standard versionwithout safety stuffing box ? Pressure-bearing body made of ductile cast iron EN-JS 1049 (0.7043)/ASTM A395• absorbs system and pipe forces • centers the valve in the pipe• optionally body made of stainlesssteel or carbon-fibre/glass-fibre-reinforced vinyl ester? Long valve neck permits optimal heat insulationwithout the installation of anelevated lever, additional stemextensions on request.Wafer-style body NKS, NKS-CLug-style body NKL, NKL-CDouble-flange body NKChlorine electrolysis optionsSpecially for use with wet chlorine gas:• Elastic insert made of Viton®instead of silicone • Body lining made of particularlypermeation-proof, modifiedTFM-PTFE instead of standardPTFE• Body nuts and bolts made ofsteel, for example, instead ofstainless steel • Tantal-coated ductile iron body?
