A coolant control valve, including: a housing with a first port and a second port; a primary rotary valve disposed within the housing and including a primary body; and a secondary rotary valve disposed within the housing and including a secondary body. The primary rotary valve and the secondary rotary valve are rotatable around the axis of rotation by at least one actuator to a first configuration. In a first configuration of the primary rotary valve and the secondary rotary valve around the axis of rotation: a first straight line, orthogonal to the axis of rotation, passes through the primary body and the first port; and a second straight line, orthogonal to the axis of rotation and co-planar with the first straight line, passes through the secondary body and the second port.
