System 8 System 8
The name System 8 stands for a modular system of solenoid coils, armature systems, solenoid operators and solenoid valves. The diameter of the armatures of all valve components is approimately 8 mm. This value is the major characteristic of this type. The components' efficiency has been increased to the optimum in years of simulation, construction and practical testing. APPLICATION OF SYSTEM 8 The solenoid operators and solenoid valves of system 8 can be used for operating 2/2- or /2 way valves, especially in pneumatics. Available switching functions are normally closed and normally open. For /2 way valves of this series, typical maimum values for operating pressure and nominal orifice are 1 bar/2. mm. 2/2 way solenoid operators and solenoid valves can also be used for controlling liquids. FUNCTION While the solenoid operator/solenoid valve is deenergized, the armature1 is being pushed down on the lower valve seat by the reset spring2. The lower valve seat is closed by a sealing element. In this switch position the upper valve seat in the magnetic core is open. When the valve is energized, the magnetic force S82 eceeds the force of the reset spring and moves the armature into the opposite etreme position. In this case the upper valve seat is closed by the sealing element, whereas the lower valve seat is open. Solenoid operators and solenoid valves have identical functionality. However, if solenoid operators are ordered, neither the lower valve seat nor the valve body is shipped. Those components have to be provided by the customer. 2/2 way valves do not have an upper valve seat. Besides that, the function of the magnet is identical.

SPECIAL REMARKS Note: The proportions of the solenoid coils displayed in the images on this page do not represent the actual proportions. The technical data are valid for the indicated standard voltages. Other voltages are available on request. Perfect function of these solenoid coils with the pertinent components included in this catalogue is assured with the winding having reached its operating temperature (ma. ambient temperature and ma. voltage tolerance). The steady-state over-temperature is reached in case of valve bodies of plastic and coil encapsulation made of Thermoplastic. All valves are designed in compliance with DIN VDE 080. Arrangement of the valves in modular design is possible, however, it may ensue a higher temperature increased by up to 20 K and may limit the function. A general lifetime of the products cannot be specified, as it is decisively influenced by ambient conditions, the single application and combination with other components. The function can only be fulfilled in case of eclusive use of nass magnet products. Should there be deviating or additional operating conditions compared to the abovementioned conditions, special testing is necessary in order to verify the usability of the nass magnet products. nass magnet will be glad to give you the required advice.
