Flight-Qualified Flow Controls
With the intense pressures they operate under and their critical role in flight, valves used in spacecraft must meet incredibly strict tolerances. No matter whether it serves as a component of the vehicle’s engine, helps pressurize the crew cabin or feeds fuel to vital systems, each valve has to be extremely reliable and capable of delivering exceptional performance in extreme conditions.
Marotta Controls offers space valves with over 60 years of flight-proven heritage. Our pressurization and control valves played a critical role in the earliest days of manned spaceflight, from the fuel control valves on the Saturn rocket to propulsion systems for the Lunar Module ascent and descent engines.
With extensive experience and success in our space system technologies we are able to leverage our heritage and product portfolio and have evolved our qualified controls to meet the increasing requirements of Space applications. Today, our pressurization and propulsion controls provide reliable, cost-effective performance without compromise to commercial and military space control systems and spacecraft.
The list of applications in which our spacecraft controls are found is extensive. It involves critical components and functions that are necessary to the safety, integrity, quality and success of spacecraft systems and missions. These applications include:

Pressure Control Mechanisms in Space Applications
Maintaining precision control over pressure in spacecraft cabins and fuel containers is crucial when operating in the vacuum of space. These valves have to be designed to meet extremely rigid requirements for performance and durability.
Another key consideration for a valve used in spacecraft is its weight. Every component that goes into a space vehicle has to be carefully engineered and manufactured to contribute as little mass as possible to the entire vehicle. Marotta Controls is proud to be able to say that our lineup of space valves continues to meet the exceptionally high standards of commercial space, just as they did in the earliest days of the American space program.
We offer an extensive line of services and support — all on-site under one roof. Our state-of-the-art facility enables us to design, develop, qualify, test and manufacture in one location, increasing our product quality and reliability while reducing lead times to protect program schedules. Our capabilities and expertise include design engineering, production engineering, development labs, assembly workstations, production cells, machine shop and a wide range of cutting-edge testing equipment.
