A diaphragm-type control valve (10) having a valve body (12) holding a diaphragm (100) and an expansion member (150) is provided preferably for use in the separation of and fluid control between a fluid source and a pressurized gas volume. An inner surface of the valve body defines a chamber having an inlet (14) and an outlet (16) in communication with the chamber, and an elongated seat member (26). The expansion member (150) biases the diaphragm (100) to a seated position within the valve. |
