1. A fuel-isolation system, comprising:
a valve body defining a flow passage extending from an inlet to an outlet, and in addition to the inlet and the outlet, the valve body defining a test port that opens into the flow passage and is fluidly connected with the outlet but not the inlet;
a rupture diaphragm integral to the valve body, the rupture diaphragm in the flow passage and fluidly sealing the inlet from the outlet;
an actuator situated adjacent the rupture diaphragm, the actuator including a plunger that is configured to move and cause breach of the rupture diaphragm and thereby fluidly connect the inlet and the outlet; and
a propellant tank having an outlet attached to or integral to the inlet of the valve body.
