A coolant control valve includes an actuator, at least one valve body, an outer housing, and a temperature sensor having a first flow state and a second flow state. The first and second flow states can be achieved by first and second axial positions of the temperature sensor.

Temperature sensor for coolant control valve

A method of sealing a coolant control valve of a cooling system for a power device which generates heat as a by-product of operation. The cooling system includes a pump, a heat exchanger, and coolant. The valve includes: an internal channel in fluid communication with the exchanger; a sealing package in contact a surface of the coolant control valve and bounding a portion of the cooling system and the channel; and a rotary element in the channel and rotatable to open and close the valve. The portion is bounded in part by the valve and the sealing package. The method includes: starting-up the device; creating a pressure differential of at least 0.2 bar between the coolant in the portion of the cooling system, and the coolant in the internal channel; rotating, using a motor, the rotary element; opening the valve; and pumping, using the pump, the coolant through the internal channel.

Method of seating a valve seal

A coolant control valve (CCV) includes an outer housing, an actuator, a valve body, and one or more thermoelectric generators (TEGs). The outer housing includes at least one inlet and at least one outlet. The TEG is operatively connected to the actuator and can be a lone source of power to the CCV or assist a primary power source. The CCV can utilize a power management device that can receive power input from either the TEG or the primary power source. The TEG has a first surface and a second surface, either of which can be exposed to air or a cooling system fluid or coolant; the coolant can be water, ethylene glycol, a combination thereof, or any other fluid that is utilized in a system that provides temperature management for a component or system.
