The present invention relates to a reducing agent injection valve of the selective catalyst reduction apparatus, in particular to a technique for controlling the flow rate of the reducing agent to be injected. Disclosed invention is a selective catalytic reduction (SCR, Selective Catalytic Reduction) in the reducing agent injection valve of the device, comprising: a first valve and a second valve connected in parallel with the injection port of the reducing agent in order to control the flow rate of the reducing agent is injected, the first the valve is a flow rate adjustable valve, the between the two valves on / when configured in the off valve state and the second valve on the through the first and second valve valve capacity (%) to 100% of the second valve If the adjustment, and the second valve is off the valve may be adjusted through the capacity of 0% to the first valve via a first valve (%). Therefore, even when injecting a small amount of a reducing agent or the like in accordance with change in the load fluctuation and the equipment conditions to fine tune the flow rate by dividing the amount of the reducing agent injection system can effectively improve the reliability of equipment.
