Flight-Qualified Flow Controls

Marotta Controls offers products 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:

  • Chemical injection
  • Engine controls
  • Ground support equipment and systems
  • Fuel purge lines
  • Launch vehicles

Space Systems

CoRe® Flow Controls

CoRe® Flow Controls series of solenoid valves is the optimal solution for complex commercial launch vehicle applications.  CoRe combines proven high-performance and high-reliability with affordability and availability.

  • High volume production capability
  • Reusable
  • Wide-range of applicable systems

Electronic Pressure Regulation

Electronic pressure regulators provide precise control to propellant feed systems and are designed to handle high operating pressures and are qualified for use in dynamic spacecraft and missile environments.

  • Up to 10,000 psi
  • Triple modular redundant
  • Scalable operation

Satellite Propulsion

Our flight qualified engineered propulsion controls are compact, lightweight, use minimal power and are compatible with storable propellants used in electric propulsion and chemical propulsion feed systems.

  • Latching and non-latching isolation valves
  • Thruster valves
  • Proportional control valves

Worldwide Standard in Solenoid Valves

With over 77 years of experience and hundreds of patented valves, we have the widest selection of solenoids as well as the expertise to design and manufacture solutions to meet your requirements.

  • Balanced poppet design
  • Customized solutions
  • Space-flight qualified

Check Valves

Check valves incorporate a poppet with internal flow passages for minimal pressure drop. These rapid response, low pressure-drop designs are ideal for applications that require a compact, lightweight package.

  • Large L/D ratio, minimal chatter
  • Smooth operation
  • Cryogenic fluids

Relief Valves

Advanced pressure relief valves for systems that contain gases and liquids in a variety of pneumatic, hydraulic and cryogenic application

  • Compact & lightweight
  • Pressure balanced poppet
  • Narrow regulation band

Our space-qualified products for the above applications include flow controls, electronic pressure regulators, flight-qualified propulsion controls, solenoid controls, check valves, relief valves, piezo regulators, isolation valves, thruster valves and more.

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.

With extensive accolades and credentials, we are proud to let our experience and success speak for itself. We:

  • Hold more than 200 patents
  • Are the only small business to win the coveted NASA George M. Low Award for Quality and Excellence — twice
  • Emphasize quality control and customer services
  • Hold quality approvals and certifications from numerous organizations, including S9100:D, ISO 9100-2015 (Revision D), AS9100, MIL-Q-9858A, MIL-I-45208 — and many, many more
