The product portfolio for a broad range of applications, including satellite propulsion, attitude control, pressurization systems and fluid management across commercial, civil and defense space programs.

CoRe Flow Controls: Compact and Scalable Valve Solutions

Marotta Controls’ CoRe Flow Controls represent a modular and highly configurable solenoid valve platform developed specifically to meet the size, mass and performance constraints of spacecraft systems. These valves are designed with a common core architecture, allowing customization of flow paths, electrical interfaces and mounting configurations without extensive redesign. This approach helps satellite manufacturers reduce non-recurring engineering effort while maintaining consistent performance across multiple mission variants. The CoRe platform supports both monopropellant and bipropellant systems, as well as inert gas applications. Built for repeatable performance and long operational life, these valves are qualified for the vibration, shock and thermal conditions associated with launch and on-orbit operations.

Electronic Pressure Regulators: Precise Pressure Control for Space Systems

Marotta Controls’ Electronic Pressure Regulators (EPRs) provide closed-loop pressure regulation for spacecraft propulsion and pressurization systems. By integrating sensors, electronics and control logic within a compact unit, these regulators enable precise pressure management throughout all mission phases from launch through end-of-life operations. The EPR design allows for real-time adjustment of output pressure in response to system demand, improving efficiency and system stability. These regulators are engineered for high reliability and are suitable for long-duration missions where consistent pressure control is critical to propulsion performance and overall spacecraft health.

Satellite Propulsion Systems: Integrated Flow Control Solutions

Marotta Controls offers a range of Satellite Propulsion Control solutions that support both chemical and cold-gas propulsion architectures. These systems integrate multiple valve functions such as isolation, regulation and relief into optimized propulsion assemblies designed to simplify spacecraft integration. The company’s propulsion control products are used in applications including orbit raising, station keeping, attitude control and deorbiting. Their modular design philosophy allows propulsion systems to be designed to specific mission requirements while maintaining compliance with stringent space qualification standards.

Solenoid Valves: Proven Performance Across Space Missions

Marotta Controls’ Solenoid Valves form the backbone of many spacecraft fluid control systems. Designed for precise on/off control of propellants and pressurant gases, these valves are qualified for repeated cycling and extended dormant periods without degradation in performance. Available in a range of sizes and configurations, Marotta solenoid valves are used across satellite platforms for propulsion, tank isolation, and system safety functions. Their robust construction and extensive flight heritage make them a trusted choice for mission-critical applications.

Check Valves: Ensuring Directional Flow and System Integrity

Check Valves from Marotta Controls are designed to prevent reverse flow within spacecraft fluid systems, protecting sensitive components and maintaining system integrity. These valves operate passively, responding automatically to pressure differentials without the need for external power or control. Optimized for low leakage and reliable sealing, Marotta check valves are used in propulsion feed systems and pressurization lines where failure tolerance is minimal. Their simple and robust design contributes to overall system reliability across the spacecraft lifecycle.

Pressure Relief Valves: Safety-Critical Protection

Marotta Controls’ Pressure Relief Valves provide essential over-pressure protection for spacecraft propulsion and pressurization systems. These valves are calibrated to open at predefined pressure thresholds, safeguarding tanks and downstream components from potentially damaging pressure excursions. Designed to operate accurately after long periods of inactivity, Marotta relief valves play a critical role in ensuring spacecraft safety during both ground handling and in-orbit operations. Their performance consistency is especially important for missions with extended storage and operational timelines.

Across the spacecraft valve portfolio, Marotta Controls emphasizes reliability, repeatability and manufacturability. All products are developed and tested to meet rigorous aerospace standards, with qualification processes that reflect real mission environments. This focus has enabled Marotta Controls components to fly on a wide range of satellite platforms and space missions worldwide.
