 2FRM type speed regulating valve is a two-way flow control valve. This valve is composed of a pressure reducing valve and a throttle valve in series. After the oil flow enters the speed regulating valve, it is first decompressed by the valve and then throttled by the throttle valve. Since the pressure reducing valve compensates the pressure of the throttle valve, the flow of the speed regulating valve is not affected by the load change. At the same time, the throttling window is designed as a thin blade, and the flow rate is little affected by temperature. When the speed regulating valve is connected in parallel with the check valve, the oil flow can flow backward. The Z4S type is integrated under the speed regulating valve, which can stabilize the flow through the speed regulating valve in both directions.
