DV type the throttle and DRV type one-way throttle valve is a more simple and accurate to adjust the speed of executive element flow control valve, when it is fully closed it is also globe valve. On the knob color scale was used to display the size of the flow control, the greater the opening of color triangle, the greater the flow. At the same time when to readjust can still be according to scale back to its original set of adjustment position.
