  • Patent number: 10982783
    Abstract: A valve is provided and includes a valve body defining a pathway, a diaphragm and a wire. The diaphragm is configured to assume first or second conditions in which the diaphragm blocks or permits fluid flow through the pathway, respectively. The diaphragm is biased toward assumption of the first condition. The wire is coupled to the diaphragm. The wire has an uncontracted length in an unheated state whereby the wire permits assumption of the first condition by the diaphragm due to the bias and a contracted length in a heated state whereby the wire pulls the diaphragm toward assumption of the second condition in opposition to the bias.
