Standard NAMUR valve VSNC - The new NAMUR generation - 1

Solenoid valves VSNC The new NAMUR generation Highlights • NAMUR connection pattern to VDE/VDI 3845 • Rotatable seal for 3/2-way or 5/2-way valve • Wide choice of Ex solenoid systems • Sturdy and powerful • Extended temperature range • Outstanding value for money • All solenoid coils can be used on an armature tube • The variant VSNC-...FN consumes less power and thus offers greater energy efficiency The standard NAMUR valve VSNC is certified worldwide in accordance with the usual explosion-protection standards and can be used in many industry segments and applications. Its distinguishing features are its modern design, durable quality and fully tested technology and materials. The valve also stands out thanks to its excellent value for money – this is what modern NAMUR valves should be! Single-acting or double-acting? Whether you are using a s ingle-acting or double-acting actuator, the standard NAMUR valve VSNC offers you the right solution with just one valve. All you have to do is turn the seal at the NAMUR interface and a 3/2-way valve becomes a 5/2-way valve. Explosive environment? Not a problem! The VSNC range includes IEC Ex-certified solenoid systems for zones 1/21 and 2/22, Class I/II/III, Division 1 solenoid systems to NEC 500 as well as solenoid systems with local certification to INMETRO, CCC-Ex and Kosha. Choice of actuation options The flexible interface of the standard NAMUR valve VSNC means you can use solenoids with device plugs or terminal boxes. If you want to connect electropneumatic pilot valves, use the CNOMO interface. With exhaust air recirculation! The integrated exhaust air r ecirculation (spring chamber protection) ensures that no atmospheric air is taken in; this protects the spring chamber and the springs of the actuator against corrosi

Solenoid valves VSNC Feature Piston spool/poppet valve Valve function, single solenoid Valve function, double solenoid 5/2-way or 5/3-way pressurised, closed, exhausted Reset method Mechanical spring Manual override Detenting, non-detenting, none Design Poppet valve The poppet valve design (VSNC-FT…) really comes into its own when the demands on the application increase. It offers better tolerance against “contaminated pneumatic air”, less leakage and fewer dynamic seals, which can have a positive effective on the service life. Piston spool valve The piston spool valve VSNC (VSNC-F…) is the...
