Nass Magnet System 8 2/2 Normally Closed Armature Assembly
Genuine Nass Magnet System 8 flange-mounted armature assembly for 2/2 way normally closed solenoid valves, suitable for Shako PU220AR-01 1/8" and PU220AR-02 1/4" direct-acting solenoid valves.
The assembly combines a brass armature guide tube with stainless steel internal components and is available with a choice of NBR, EPDM, FKM (Viton) or HNBR seals, allowing the valve to be configured for different compatible fluids and operating conditions.
Designed for use with Nass Magnet System 8/22 and 8/30 solenoid coils, the 2/2 NC version supports coil power levels 3, 4, 5 and 6 and can be used with both AC and DC operation. The manufacturer's System 8 data confirms the 2/2 NC brass-guide version supports these four power levels.
Armature Function & Operation
Function: 2/2 way normally closed
Operation: Direct acting solenoid armature
Connection: Flange fitting
Armature guide: Brass
Internal components: Stainless steel
Operating pressure: 0–10 Bar*
Electrical operation: AC or DC according to fitted coil
Mounting position: Any position, with the manufacturer recommending the plunger in the vertical direction where possible.
Seal Options
Available with:
✓ NBR – Standard
✓ EPDM
✓ FKM / Viton
✓ HNBR
Selecting the correct seal material is important and should be based on the operating media, temperature and application.
Nass Magnet Coil Compatibility
Compatible with Nass Magnet System 8 solenoid coils including:
✓ System 8/22 Coils
✓ System 8/30 Coils
✓ Power Level 3
✓ Power Level 4
✓ Power Level 5

Shako PU220AR Compatibility
Designed as a replacement armature assembly for:
✓ Shako PU220AR-01 – 1/8"
✓ Shako PU220AR-02 – 1/4"
This makes the assembly ideal for servicing or rebuilding existing PU220AR direct-acting solenoid valves without replacing the complete valve.
Construction
Armature guide tube: Brass
Internal components: Stainless steel
Connection type: Flange
Ambient temperature: -10°C to +50°C
The System 8 design allows the armature assembly and coil to be replaced independently, reducing maintenance cost and allowing different electrical coil configurations to be fitted to the same compatible valve body.
Typical Applications
✓ Compressed Air
✓ Water
✓ Vacuum
✓ Compatible Gases
✓ Compatible Liquids
✓ Oils & Fuels With Suitable Seal
✓ Industrial Automation
✓ Process Control
✓ OEM Equipment
✓ Solenoid Valve Repair
Always select the seal material appropriate to the operating media.
Replacement & Maintenance
This armature assembly is particularly useful for repairing Shako PU220AR Series solenoid valves where the valve body remains serviceable but the plunger, seal or armature assembly requires replacement.
With the appropriate Nass Magnet System 8 coil fitted, the valve can be configured for a wide range of AC and DC supply voltages without changing the complete valve assembly.
