Abstract
A valve unit (1.1, 1.2, 1.3) for modulating pressure in a compressed air braking system has an inlet valve (6) configured as a diaphragm valve, an outlet valve (7) configured as a diaphragm valve, and respective precontrol valves (8, 9), which are each configured as a 3/2-way solenoid valve and are arranged in an elongate valve housing (2), which is divided by a division plane (10) that is largely horizontal in the installation position into a base housing (11) and a housing cover (12). The precontrol valves (8, 9) are arranged in the housing cover (12) in the longitudinal direction (13), and the housing cover (12) has a centrally arranged magnet module (20) and two air guide modules (23, 24) adjacent to the magnet module (20) in the longitudinal direction (13) and connected via a single connecting element (45) both to each other and to the base housing (11).
