• Valve housing:

    The valve housing has a defined pneumatic interface

  • Valve seating:

    (see nominal opening size) Nozzle in the valve system/valve solenoid that affects the discharge and flow characteristics

  • Valve solenoid:

    Consists of an armature system, a solenoid coil and possibly fixing material

  • Valve system:

    Consists of an armature system and valve housing with corresponding pneumatic interfaces

    • KR – Concentric O-rings
    • GKR – concentric O-rings with trapped exhaust air
    • CNOMO – CNOMO hole pattern
    • SF – side-mounted flange
    • FL – flange mounting on the underside

  • VDE:

    German Association for Electrical, Electronic and Information Technologies

  • Vent protection unit:

    Serves to direct the flow of escaping air after the valve has been switched off

  • Voltage:

    Gives the value for a device to which the operational and power characteristics are related

  • Voltage tolerance:

    Gives the permissible voltage deviation value


  • Winding:

    Describes the number of windings with laquered copper wire on the solenoid coil
