Purpose and characteristics 

The FL/LDF Throttle Valve and One-Way Throttle Valve are simple flow control valves. The throttle valve regulates the flow rate by changing the opening of throttling port. When the oil flows forwardly, the one-way throttle valve works to throttle the flow. When it flows backwardly, it works as a check valve, so that the oil freely flows through the throttle valve.
