Seat Valve electr. direct
Series 3/045
Valve 3/045-49/0815/5278-4L AC
3/2-way change-over valve type 3/045 as a universal valve for distributing and mixing gaseous and liquid media. By closing one of the three ports, the valve can perform a 2/2-way function. Which port is closed depends on whether an NC or NO function is required in the process application. The special feature of this valve design compared to conventional seat valves is that the valve function is guaranteed even when the medium flows through from all directions. The armature chamber is separated from the medium.
