Abstract

A valve control unit, particularly for a pressure modulator of a commercial vehicle includes a valve control housing, solenoid valves, which are provided with solenoids and internal valve pieces inserted into the solenoids, and a pneumatic interface. The solenoids are accommodated inside the valve control housing. Pressure sensors for measuring pneumatic pressures are accommodated in or on the valve control unit, preferably on the top surface. Valve bores, into which the internal valve pieces are inserted, extend within the valve control housing. Air ducts extend between the pneumatic interface, the valve bores, and the pressure sensors, inside the valve control housing. The solenoids and pressure sensors are contacted with an electrical interface. The valve control housing can be a single piece.
