The item of MTCV03 series are flow regulating valve is under a certain pressure difference, by changing the size of the orifice to control the hydraulic resistance of the flow orifice, thereby regulating the implementation of components (hydraulic cylinder or hydraulic motor) speed of the valve. Flow regulating valve including throttle, governor valves, throttle valve and divert rainwater overflow valve.
There are two ways of flow control, meter-in and meter out, the meter in is one-way flow control valve control the speed of the drive in two ways namely, inlet of the (meter-in) and outlet throttle (meter-out). Inlet of the flow regulating valve that is set to control the oil into the oil flow to adjust the compression cylinder speed, also known as oil into the throttle, the speed control in this way, such as a slight change in the piston rod of the load, speed, poor stability, it is only for single-cylinder, small hydraulic cylinder or short stroke hydraulic cylinder speed control.
The Meter-out of flow that is the size of the control to adjust the speed of piston movement, also called oil discharge throttling back pressure of sport in this way to limit the speed, so speed stability, good, commonly used in the double-acting oil pressure cylinder speed control.
Note that a small hydraulic cylinder and hydraulic cylinder short stroke because they do not drain quickly in the pressure side of savings (generated back pressure), it must import throttle.
