4003/2 and 5/2-way I.S. Solenoid Valvefor pneumatic applications6519 NAMURI.S.Type 6519 NAMUR EEx i can be combined with...• NAMUR flange mounting• Intrinsically-safe operation• 5 or 3-way function• Corrosion-resistant versionfor outdoor use• ATEX approvedBarriersRemote I/OProcess valvesApprovalsThe Type 6519 NAMUR I.S. valve is used for thepneumatic control of double or single-acting actuatorswith a NAMUR adapter plate flange. The circuit functioncan be changed using a change-over plate. In the 3/2-way function, feedback of the exhaust air takes place inthe spring area of the armature drive. The diaphragmcontrolledvalve seats work with very low friction,ensuring reliable switching of the valve even after longshutdown periods and at ambient temperatures below0 °C (32 °F). The valves work without a continuousair consumption, and the use of high quality materialsmakes it possible to used these valves in the open airand under chemical atmospheres.Note:The units may only be used in explosive atmospheresin the manner approved by the Federal Institute ofPhysics and Technology (PTB), i.e., the permissiblemaximum electrical values must be complied with.Suitable barriers and isolating modules are availablefor this.PLCBarrier/isolatingcomponentTechnical dataOrificeBody materialElectrical dataDN 6.0 mmPilot valve Stainless steel 1.4305 (303)Main valveSeal materialMediaAmbient temperaturePneumatic connectionPolyamide, glass-fibre reinforcedFKM, NBR and PURLubricated or unlubricated compressed air,instrument air, nitrogen-25 °C to +55 °C (-13 to 131 °F)Supply ports 1, 3, 5 Threaded port NPT 1/4Service ports 2 and 4 NAMUR adapter plate acc. to VDI/VDE 3845Electrical connection Tag connectors acc. to DIN EN 175301-803Ambient conditionsProtection class(previously DIN 43650), Form A for connector Type2508 (see Accessories).
