Solenoid Valves

What is the Nass Magnet System?

The Nass Magnet name "system" stands for a specific range of modular solenoid coils, solenoid valves and solenoid operators. The armature diameter of all valve components are based around specific dimensional scales, which has been calculated upon optimum component efficiency based on years of function testing through simulation and practical testing.

Why Nass Magnet have different systems?

The diameter of the armature is a major determining factor in technical selection and is in combination of the power level which for AC (Alternating Current) is measured in VA (Volts Amps) for both Inrush and Holding currents and in the case of DC (Direct Current) Watts.

Different liquid or Gas control system applications will require different flow rates (orifice sizes or Nominal Diameter), Pressures, Media or Ambient Temperatures, Electrical Power limitations and function. Nass Magnet are world leaders in discovering and delivering powerful magnetic valves, magnetic systems and electrical protective connectors for safe and hazardous area applications. 

What Nass Magnet Systems are available?

Below are the new Nass Magnet product catalogues and Nass Magnet newly released revised part numbers for the standard production system 6, 8, 13, Tiny Tube and ATEX area PDF catalogues.

Nass Magnet System 6 Solenoid Coil

Nass Magnet System 6 Solenoid Coil

Nass Magnet system 6 is based around 6.0 mm armature assembly.

The solenoid operators and solenoid valves of System 6 can be used for operating 2/2- or 3/2 way valves. Available switching functions are normally closed and normally open. For 3/2 way seat valves of this series, typical maximum values for operating pressure and nominal width are 10 bar/1 mm. For 2/2 way devices, a maximum operating pressure of 16 bar or a maximum nominal width of 1.8 mm can be achieved. The components of System 6 are mainly used as pilot valves in pneumatics. The solenoid operators and solenoid valves are designed for the use with compressed air or other neutral gases. The use of other substances is possible according to prior agreement with Nass Magnet.

Nass Magnet System 8 Solenoid Coil

Nass Magnet System 8 Solenoid Coil

Nass Magnet system 8 is based around 8.0 mm armature assembly.

The solenoid operators and solenoid valves of system 8 can be used for operating 2/2- or 3/2 way valves,
especially in pneumatics. Available switching functions are normally closed and normally open. For 3/2 way valves of this series, typical maximum values for operating pressure and nominal orifice are 16 bar/2.5 mm. 2/2 way solenoid operators and solenoid valves can also be used for controlling liquids.

Nass Magnet system 13 is based around 13.0mm armature assembly.Nass Magnet System 13 Solenoid Coil

Nass Magnet system 13 is based around 13.0 mm armature assembly.

The solenoid operators and solenoid valves of system 13 can be used for operating 2/2- or 3/2 way valves, especially in pneumatics and process technology. Available switching functions are normally closed and normally open. For 3/2 way valves of this series, typical maximum values for operating pressure and nominal width are 40 bar/5 mm. The solenoid operators and solenoid valves are designed for the use with compressed air or other neutral gases. 2/2 way solenoid operators and solenoid valves can also be used for controlling non-aggressive liquids.

Nass Magnet System Tiny Tube ValveNass Magnet System Tiny Tube Valve

Nass Magnet system Tiny Tube is based around 6.0 mm armature assembly.

The so-called Tiny Tubes are our smallest valves. Besides their small physical dimensions, they feature respectable pneumatic power density and a long life time. Even though they are not part of a modular system, there is a versatile product portfolio of application- specific “plug & play” solutions. All of the compact valves are micro-calibrated in order to attain constantly high flow rates in the automation industry. Attractive for medical application: Nass Magnet provides a special version of the Tiny Tubes for a lubrication-free operation with Teflon-coated components.

Encapsulated and Intrinsically Safe Solenoid Operators

These solenoid operators were tested by the Physikalisch-Technische Bundesanstalt (PTB) according to the directive 94/9/EC. They are generally suited for single and block assembly. Specific instructions and remarks for safe operation can be found in the respective operating instructions. Explosion protection can only be realized if the respective components shown in this catalogue are used. The maximum operating pressure for the armature/valve system is 12 bar. Solenoid Operators with Increased Protection, Non-Igniting These solenoid operators were tested by nass magnet according to the directive 94/9/EC. Explosion protection can only be realized if the respective components shown in this catalogue are used. The maximum operating pressure for the armature/valve system is 12 bar.

Special Advice in using EX-Solenoid Coils

Ex-zones specify locations with a dangerous and potentially explosive atmosphere based on the following criteria:
Zone 0 for gases: present permanently or on a long-term base (more than 1.000 hours per year); this includes the inside of a tank container of a vehicle transporting hazardous goods, for instance.
Zone 1 for gases: occasionally present (10 to 1.000 hours per year); this includes the filling area between the subsurface tank of a gas station and a fuel tanker lorry or wagon, for instance.
Zone 2 for gases: present only on rare occasions and on a short-term base (less than 10 hours per year); this includes the drive-through area in between the fuel dispensers of a gas station, for instance.
Zone 20 for dust: present permanently or on a long-term base (more than 1.000 hours per year) in a cloud-like fashion; this includes the inside of the silo of a flour mill, for instance.
Zone 21 for dust: present occasionally through the raising of settled dust (10 to 1.000 hours per year); this includes the outer filling area of the silo of a flour mill, for instance.
Zone 22 for dust: present only on rare occasions and on a short-term base (less than 10 hours per year); this includes minor dust debris on pipe plugs, for instance.

The European Standard EN 60079-0 comprises generic regulations for construction type and concurrent validation of electrical equipment to be applied on hazardous areas. It refers to further standards, which e.g. define the ignition protection type. The actual ignition protection type is distinctly coded on the equipment.
Name Standard Remarks
Encapsulation of oil (o) EN 60079-7 Regarding the explosion-proof type encapsulation of oil, the device or part of it are separated from the explosive atmosphere.
Encapsulation of overpressure (p) EN 60079-2 An explosion-proof gas being under overpressure (min. 0,5 mbar) shields the ignition source and avoids the penetration of the surrounding atmosphere.
Encapsulation of sand (q) EN 60079-5 The fine-grain filling material shields the ignition source Orderly used, an arc created inside may not ignite the ex-atmosphere surrounding the body.
Pressure-resistant encapsulation (d) EN 60079-1 In case of ignition inside the encapsulation, the body must resist the pressure, and a transmission of the inner explosion to the outside must be excluded.
Increased safety (e) EN 60079-7 The explosion-proof type (e) is only valid for equipment or parts of it which, under normal circumstances, do neither create sparks nor arcs, do not reach hazardous temperatures and the nominal voltage of which does not exceed 11 kV.
Intrinsic safety (i) EN 60079-11. The energy inside the circuit is limited to values which do not allow inadmissibly high temperatures and/or sparks respectively arcs.
Nonincendive (n) EN 60079-15 Simplified application of the other explosion-proof types for zone 2 Protection by encapsulation (m) EN 60079-18 The ignition source is embedded into a sealing compound in such a way that it cannot ignite a hazardous explosive atmosphere.
