A valve arrangement includes an operating valve arrangement in the form of a relay valve and a control valve arrangement. The control valve arrangement includes a controlled inlet valve and a controlled outlet valve. Solenoid valves are provided for selectively routing pressure medium. A first control piston and a second control piston, which can be subjected to pressure by a pressure medium via operation of the solenoid valves, control actuation of the inlet valve and the outlet valve of the control valve arrangement. The control valve arrangement is installed directly on the housing of the operating valve arrangement to achieve a compact structural unit and to reduce the amount of pressure medium channels and pressure medium connections required. The operating valve arrangement and the control valve arrangement are designed such that parts of the control valve arrangement are located in, or constituted by, the operating valve arrangement. The pressure medium outlet of the control valve arrangement is connected to the pressure medium outlet of the operating valve arrangement, thereby permitting use of a single noise suppressor for the valve arrangement to suppress the exhaust noise.
