The Spacebus 4000 can support satellites weighing up to six metric tons and delivering 16 kW of power with 120 onboard transponders.
VACCO designs, develops and maintains a full line of fill & drain valves to satisfy the needs of the space and missile industries. From high pressure to low pressure, standard to miniature to micro, and gas to propellant, VACCO fill & drain valves are manually operated, incorporating the VACCO-pioneered anti-rotation, rising stem feature.
VACCO fill & drain valves achieve extremely tight leakage, while offering two or three seals to provide redundant inhibits against external leakage.
¼” High Pressure Gas Fill & Drain Valve
Propulsion systems, like Alcatel Spacebus Unified Propulsion System (UPS) and Plasmic Propulsion Subsystem (PPS), use VACCO’s ¼” High Pressure Gas Fill & Drain Valve for filling and draining helium and Xenon gases before launch and during ground testing.
