Pneumatic Firing Valves

Pneumatic Firing Valves

Pure Power. Consistent Shots.

Our high-performance pneumatic firing/ ejection valve technology powers next-generation smartbombs. These firing/ejection valves use high-pressure air to release the weapon. As a key component of the Small Diameter Bomb program, Marotta Controls designed, developed, qualified and supplied these firing/ ejection valve systems to power the SDB’s next-generation stores ejection racks.

Marotta’s Pneumatic Ejection Valve Manifold Assembly system consists of a firing valve, integral accumulator, relief valve, manual vent valve, integrated latch points, pitch control valve and dual outlet ports all in a high performance package.

Capability Impact

  • Higher ejection force allows release of stores at higher speeds
  • Pneumatic power provides consistent shot-to-shot ejection profiles

Efficiency Impact

  • Clean air powers the rack, eliminating the need for frequent cleaning which is a common problem with pyrotechnic charges
  • Cost efficient – because it’s reusable, there’s no need to replace costly squibs after each mission
  • Reduces logistics problems by eliminating the need to acquire and store pyrotechnic devices
