What Space Solutions does

Space Solutions Co., Ltd. ((주)스페이스솔루션), founded in 2000 in Daejeon, South Korea, is a privately held precision fluid-control manufacturer serving aerospace, defense, and select industrial customers. Its product portfolio spans welded and formed metal bellows, vacuum and specialty valves (lock, latch, solenoid, cryogenic, high-temperature, UHP/globe), accumulators and tanks, and complete propulsion subsystems — H2O2 monopropellant thrusters (50–250 N), bipropellant engines (1,200–2,500 N), and xenon feed units for satellite electric propulsion. Technical differentiators include ultra-low leak rates (1×10⁻¹¹ atm-cc He/sec), >1,000,000 cycle durability, an operational envelope of −260°C to 1200°C, and qualified use across KSLV-II (3rd stage attitude control), KF-21 (ECS duct), T-50, KUH, and Korean satellite platforms.

The firm generates revenue through B2B hardware sales of components and integrated subsystems, supplemented by engineering and manufacturing-process services (brazing, welding, hot-forming, helium leak testing) and technical staffing services. Customers are concentrated among Korean primes and government/defense agencies — Korea Aerospace Industries (KAI), Agency for Defense Development (ADD), Korea Aerospace Research Institute (KARI), and KAIST — with exporting activity to Japan (KITZ valve AIT contract) and exhibition-led entry into semiconductor equipment OEMs. Go-to-market is direct enterprise sales with quote-based pricing, supported by multi-language catalogs and SEMICON exhibitions.

Operations are organized across seven South Korean sites: Daejeon headquarters (R&D, clean room, manufacturing), three additional factories (Gwanpyeong, Asan #1 defense/industrial, Asan #2 industrial/logistics, and Gunsan processing), and a Yongin sales branch. Reported annual revenue was over 30 billion KRW (~USD 25M) in 2022 with USD 7M+ in export sales, and management's Vision 2027 targets 100 billion KRW at 10% operating margin. AS9100 (UKAS-accredited), ISO 9001:2019 and ISO 14001 certifications, plus approved-supplier status with KAI, constitute the principal regulatory moat; an accumulated patent portfolio (Lock Valve, High-Temperature Valve, Bellows with Bearing, Sandwich Bellows Engine, High-Pressure Self-Locking Valve, etc.) and technology transfers from ADD provide a complementary intangible-asset moat.
