Abstract:
A valve for use in an air exchange panel (20) of a transportation refrigeration system is provided including a valve cap (102) configured and arranged to be positioned adjacent the air exchange panel (20) and movable between a first position and a second position. The valve cap (102) includes a magnetic portion. A resilient flexible member (110) is coupled to the valve cap (102) and is configured and arranged to be coupled to the air exchange panel (20). The resilient flexible member (110) biases the valve cap (102) into a first position. An electromagnet (150) is positioned inside the air exchange panel (20), opposite the valve cap (102). A controller is coupled to the electromagnet (150) to selectively apply power to move the valve cap (102) between the first position and the second position.
