Valve arrangement for compressed air braking systems

The valve arrangement has a housing (2) with a connection (3) for delivering compressed air, a connection for a line leading to a load and electrically driven magnetic inlet (6) and outlet (8) valves. Further inlet and/or outlet valves can be fitted to the housing in parallel with the first valves and multiple identical parallel valves can be driven selectively individually or in common for large throughputs according to the control philosophy.
