Abstract: A modular valve unit for controlling the flow rate of an intake or exhaust gas of a combustion engine through the passage of a valve, the valve unit comprising a valve having a valve housing (1) and at least one valve flap (2). The valve unit further comprises an interface (3) and an adapter (6), the interface (3) being connected to the valve housing (1) and having a support (32) and an engagement portion comprising at least two engagement legs (31) projecting from the distal end of the support (32) and being directed away from the valve housing (1). The adapter (6) has a connection plate (62) having at least two engagement orifices (61) for receiving the engagement legs (31) of the interface (3) and a mounting portion for holding an actuator (7). The at least two engagement orifices (61) of the connection plate (62) of the adapter (6) are each configured to engage the corresponding at least two engagement legs (31) of the engagement portion of the interface (3).

Abstract: A valve unit with a valve having a valve shaft with a rotational axis. The valve unit including an actuator having an actuator shaft with a rotational axis. The valve unit includes a mechanical coupler for rotational coupling of the actuator shaft and the valve shaft. The mechanical coupler includes a rotational axis coinciding with the rotational axis of the actuator shaft and the rotational axis of the valve shaft. The valve unit includes a first rotational member coupled to the actuator shaft and a second rotational member coupled to the valve shaft. The valve unit includes a bridge element. The first and the second rotational members include slots for receiving engagement pins of the bridge element.
