Customization overcomes defects, and now it's time to go into space! - Ultra-Compact Thruster Valve

Howe Industries is a start-up company in Arizona, USA, that develops propulsion systems for satellites and other spacecraft. The propulsion system is a system that includes small rocket engines (thrusters) used to control the satellite's orbit and attitude.

They are considering possibly installing our HVA micro valves in their developing thrusters.

Their thrusters are expected to be environmentally friendly and more efficient as the demand for nano-satellites grows since they use mainly water instead of conventionally harmful propellants like hydrazine.

Space Valves that need to be more reliable

When they used similar valves from other manufacturers before, the standard connection lengths of these valves did not match their desirable design. So, before installing the valves in the system, they had to cut the connections (pipes) in-house after purchase.

However, chips were generated during the cutting process and they got inside the valve, then interfered with normal performance of these valves. The generation of such foreign objects is fatal, especially in space valves that require precise control.

Challenge and Solution

Howe Industries initially intended to cut our valve pipes in-house, but when we told them we could customize the pipe lengths to their requirements, they were delighted and accepted our specified custom valves.

They will save themselves the trouble of internal cutting and integrate a reliable valve into their equipment.

We hope this custom valve will be integrated into their thruster and make an actual space flight in the near future...
