The fluid coupling type TV..F is a constant-filled coupling used in drives for armored face conveyors, transfer conveyors and crushers. Centrifugal valves control the filling and draining of the working circuit of the coupling and thus the power transmission. The motor starts up almost load-free, even in the event of voltage drops. The coupling torque is relieved shock-free and continuously until the required breakaway torque of the system is built up. This allows overloaded driven machines to be started up.

The driven machine starts up extremely gently and the increase in torque is dependent upon the load. The coupling also protects the drive against overload and dampens torsional vibration. This protects your system and increases its productivity.

We offer fluid couplings with operating medium as water (type TWV..F) especially for potentially explosive atmospheres or with outer casing made from spheroidal cast iron (type TUV..F) for use in operations with respective material requirements.
