ABSTRACT:
A device for controlling fluid flow for heating or cooling an associated system is provided. The present invention includes a housing having a flow control member that includes a bendable portion. The flow control member responds automatically to a pressure condition within the housing and opens or closes based on the direction and quantity of fluid flow and does not include any mechanical or electromechanical control components. The bendable portion may include, for example, a convoluted section. The flow control member is in an open position during a mode of operation of the associated system and is in a closed position in another mode of operation of the system.
