A valve device (), of a pneumatically actuatable friction clutch engageable by spring force, includes at least one inlet valve () connected on the input side to a pressurized supply line and on the output side to an actuating cylinder of the friction clutch. A pressure-sustaining valve () is upstream or downstream of the inlet valve and is designed as a check valve closing in the backflow direction. The pressure-sustaining valve is a springless check valve and includes a housing ring () having a retaining basket (), a closing element (), and a valve seat (). The closing element, in the depressurized state and with a positive pressure gradient is held in the retaining basket () of the housing ring () and, with a negative pressure gradient is pressed out of the retaining basket () and against the valve seat ().
