A valve system for the pre-engagement unit of a vehicle braking pressure modulator contains solenoid valves, which are controlled by an electronic braking system. Pneumatic pressure is fed into a brake cylinder on the vehicle wheels via a pressure regulating channel of the pre-engagement unit. The solenoid valves are configured as cartridge solenoid valves, so that assembly is simplified, and utilization of elastic tolerance compensating elements is unnecessary. A preferred embodiment includes three cylinder bodies connected end-to-end with no increase in cylinder diameter. This embodiment enables the use of identical armatures and identical magnet coils for different valve types, such as 3/2-way solenoid valves or 2/2-way solenoid valves. Also, these valves may be configured as normally open or normally closed, with identical outside dimensions. As such, three cartridge solenoid valves can be combined into a compact triple valve cartridge unit that further simplifies the assembly process.
