A control device for pressurized fluids includes a valve mechanism actuated by a first device incorporating electromagnets in a first housing, and a second device incorporating a circuit board for controlling the valve mechanism in a second housing. Pins on the first device and sockets on the second device automatically form an electrical plug-type connection when the housings are joined. Each socket is received in a first portion of a through-hole provided in a mount supported on the circuit board such that it extends into a corresponding through-hole in the circuit board. A second portion of each through-hole in each mount has a funnel-shaped guide opening toward the pins. A pressure sensor supported by the circuit board forms a plug-type engagement with a port extending from the valve mechanism when the housings are joined. Contacts extend from the sensor into holes in the circuit board.

A pre-engagement unit for a braking pressure modulator for a pressure regulating circuit includes a first pneumatic inlet, a second pneumatic inlet, a first pneumatic output terminal, and a second pneumatic output terminal. The unit includes an electrically actuated valve system having a plurality of solenoid valves and a plurality of electrical terminals connected to output terminals of an electronic control unit. An electric braking command signal transmitter delivers a driver initiated electric brake value setting to an input of the electronic control unit. Under normal conditions, a supply pressure and a redundancy pressure are delivered at the first pneumatic output terminal to be converted by an air quantity augmenting relay valve to a braking pressure. In case of failure of the electronic braking system, the redundancy pressure is delivered at the first pneumatic output terminal to be converted by the air quantity augmenting relay valve to the braking pressure.
