The invention relates to a valve device for controlling a flow of a fluid through a fluid channel, having a tube (2) made of a flexible material, in which a section of a fluid channel is formed, a valve component (1) assigned to the tube (2), a cantilevered arm (8), which is designed to be reversibly displaceable on the valve component (1) against a restoring force supplied at least partially by the cantilevered arm (8) itself, a squeeze element (10), which is arranged on a distal end of the cantilevered arm (8) for support of the cantilevered arm (8) on the valve component (1) and is configured to control a flow of a fluid through the fluid channel by pressing against an outside surface of the tube (2), optionally up to the closing of the fluid channel, and an actuator (11) which is configured to displace the squeeze element (10) in various control directions against the restoring force on the cantilevered arm (8), so that the pressure of the squeeze element (10) on the outside surface of the tube (2) and thereby the flow through the fluid channel can be regulated. In addition, the invention also relates to a system having at least one valve device and a pressure-applying device as well as a multi-way valve device having multiple valve devices.
