A pressure regulator includes a housing, a divider, and a valve. The housing includes an inlet and an outlet. The divider separates the housing into a first chamber and a second chamber. And the valve includes a spherical valve ball and a seat. The spherical valve ball is fixed with respect to a first one of the housing and the divider, and the seat is fixed with respect to a second one of the housing and the divider. A first configuration of the spherical valve ball with respect to the seat substantially prevents fluid communication between the inlet and the outlet, and a second configuration of the spherical valve ball with respect to the seat permits fluid communication between the inlet and the outlet.
