A novel fabrication process of the main valve spool in the pressurization feeding system for new generation launch vehicle has been reported in this paper. The newly-developed process improved the traditional technique, and passed the performance tests of the cryogenic safety valve at room temperature and liquid nitrogen temperature respectively, and the vibration test at room temperature. Both the sealing problem and the possible clamping stagnation of oriented-pole of the main valve spool have been solved. This developed technique has been successfully applied in the valves for new generation launch vehicle.
