Abstract
A coolant control valve unit includes a wall including a passage disposed at a predetermined position from one surface to another surface, a valve disposed to be inserted into the passage and open and close the passage according to a movement position, and an actuator opening and closing the passage through the valve by pushing or pulling the valve by using a stem connected with the valve, wherein one side and another side of the wall are formed to have a height difference in a movement direction or in an opposite movement direction so that a portion of the passage is opened and a remaining part of the passage is closed by the valve when the valve moves along the passage.
