Wessel - Model TCV -Throttle Check Valve
The throttle check valve TCV is generally suitable for setting the movement speed in a certain flow direction. Another application is to prevent cavitation and thus too high extending speed of cylinders, which are caused by pulling loads.

If an excavator picks up heavy loads with the bucket, there is a risk of cavitation on the bottom side of the stick cylinder when lowered. The reason is that the load forces the cylinder to extend quickly, but the main control valve does not deliver enough oil to the bottom side. Anti-cavitation valves prevent this! Excessive extending speeds are prevented by an adjustable resistor. A check valve allows lossless oil entry into the cylinder
