If no overpressurization occurs, the test proceeds.
Serving as a fuel-air mixing chamber, and as a mounting point for other engine components, the large manifold (430 by 280 by 90 mm), in addition to being of lighter weight than aluminum, is designed to withstand cyclic vacuum fatigue ([greater than]1 million cycles at 85 kPa); overpressurization events; tensile, flexural, and compressive creep; and impact loading resulting from mishandling.
Second and third valves maintain a positive shut-off to prevent leakage and overpressurization of the downstream valve stations.

These mechanisms may include direct exposure (primary blast injury) to the overpressurization and negative pressure waves of the explosion, which can strike the body at a velocity >300 m/s, equal to the speed of sound in air.
We designed the FlowMax with one pressure rating [250psig] on all components to avoid complicated start-up procedures and the risk of overpressurization of the actuator.
