Abstract

The invention relates to a valve cartridge for a solenoid valve, having a capsule, a magnetic armature that is movably guided within the capsule, a valve insert that is inserted into the capsule at a first end, and a valve body, which is pressed into a second end of the valve insert and has a main valve seat. The magnetic armature, moved by a generated magnetic force, moves a tappet guided within the valve insert. The tappet has a closing element with a sealing element which plunges into the main valve seat of the valve body in a sealing manner for carrying out a sealing function, and an associated solenoid valve. According to the invention the valve insert is configured as a one-part slotted bushing, and the valve body is configured as a bonnet-shaped bushing. The valve body configured as a bushing is pressed into a second end of the valve insert configured as a slotted bushing such that the main valve seat is disposed within the valve insert.
