Description
Nass Magnet System 8 Ex ia Armature Assembly
Genuine Nass Magnet System 8 armature assembly for 2/2 and 3/2 way normally closed solenoid valves using a Power Level 1 intrinsically safe Ex ia solenoid coil.
Designed for use with the 24V DC Nass Magnet System 8 Ex ia coil, this assembly provides the magnetic armature, guide tube and valve sealing components required for intrinsically safe solenoid valve applications.
Suitable as a replacement armature assembly for compatible PU221 2/2 way and PU321 3/2 way normally closed ATEX solenoid valves.
