Solenoid Valves for In-Space Propulsion
Leveraging from over 77 years of experience in designing, developing and manufacturing solenoid valves for Aerospace systems, our engineering team developed a series of micro-propulsion flow controls for satellite systems.
Marotta’s miniature solenoid valves include latching and non-latching variants to meet the requirements of both high and low pressure systems found in satellite propulsion systems. In the harsh environment of space, with the exacting requirements of mission-critical components, flight-qualified miniature valves from Marotta have proven time and again to be up to the task of precision for in-space propulsion flow control. In space applications, efficiency in size, weight and power usage are of paramount importance. Our mini solenoid valves meet these requirements, delivering reliable, robust construction in a compact package that can operate in low power scenarios.
Small solenoid valves are among the most important components in satellite and aerospace applications, better ensuring the continued proper operation of propulsion systems, XFC systems, in-situ cleaning systems and more. As miniature solenoid valve manufacturers with decades of experience in high-profile space and satellite applications, we are ready to provide the high-reliability space valves you need.

Benefits of Our Miniature Solenoid Valves
We’re known throughout the industry for designing and manufacturing the most robust high- and low-pressure miniaturized solenoid valves. We’re proud to be the manufacturer trusted by many of the world’s most demanding and exacting industries.
Beyond core performance specifications, these miniature solenoid valves are engineered to withstand the mechanical and environmental stresses associated with launch and on-orbit operation. Each design accounts for vibration, shock, thermal cycling, and vacuum exposure to help ensure long-term stability in demanding spaceflight conditions. This focus on structural integrity and environmental robustness supports consistent valve actuation and sealing performance throughout the mission lifecycle, reducing risk in propulsion subsystems where failure is not an option.
Even in the most challenging environments and applications, our satellite propulsion valves deliver exceptional performance along with numerous advantages, including:
- Compact Design: We provide the smallest space-qualified solenoid valves available on the market today. This means they are crucial for applications in which space may be limited. Despite their small size, these still can be counted on for industry-leading reliability and durability.
- Low Power Consumption: Because our valves are bistable, they require minimal power to open and close. This means they will minimize energy usage and generate relatively little heat compared to other valves.
- High-Pressure Compatibility: Their reliable performance under even the most demanding conditions makes these the absolute best miniature high-pressure solenoid valves found anywhere.
- Oxygen Safety: Our miniature valves meet stringent oxygen compatibility requirements, making them the safest and most reliable choice for use in oxygen-rich environments.
- Cleanliness: These perform extremely well in applications in which contamination is a prime concern, thanks to designs and materials that meet some of the strictest cleanliness requirements.
