Shipboard Controls
Marotta Controls is the comprehensive source for marine flow control systems. Our range of marine flow systems includes submarine controls and more to support mission-critical applications.
Every US Surface Combatant and Submarine goes to sea with Marotta valves and marine controls serving in mission-critical applications. Marotta Controls designs, develops, manufactures and qualifies high-performance motion and flow control solutions for surface ships, submarines and deep submergence vessels.
Our components and systems meet stringent naval requirements and MIL standards for shock, vibration and low acoustic signature as well as resistance to seawater corrosion. We have pioneered next-generation technologies that use advanced materials and embedded electronics to reduce the weight, life cycle cost, size and corrosion sensitivity of these critical parts.
With an extensive range of marine controls and components for marine systems, Marotta products are used in a broad cross-section of key applications. Learn more about these products and applications below.

Valve Manifolds
Manifold offerings range from simple single inlet to multiple outlets, to multi-chambered marine fuel manifolds with integral valves. Our manifolds are of single block or “building block” construction, and all valving is plug-in type.
- Configuration control: Offers greater flexibility
- Space-saving designs: Optimized for limited spaces on marine vessels
- Quieting manifold technology: Reduces noise to improve stealth and crew comfort
Motor Operated Valves
Developed specifically for maritime applications, our controls can work with DC brushless, servo and proportional control systems with a variety of power, torque, speed and positioning requirements.
- Resists seawater corrosion: Ensures longevity and reliability in the harshest marine environments
- Solid-state electronics: Offers greater durability and better energy efficiency
- 25-year service interval: Long-lasting performance cuts down on maintenance requirements
Control Actuation Systems
Designed for challenging naval environments, electromechanical actuation systems are capable of sustaining high angular velocity at high torsional load levels. All mechanical, electronic and software elements are fully integrated.
- Accurate fin position control: Provides precision control for optimal performance
- High stiffness – low backlash: Ensures consistent flow for better operation
- High bandwidth: Better performance than systems from other manufacturers
Piezo Actuated Valves
Advanced piezo technology can control flow parameters in real time and adjust orifice size to meet your desired flow and pressure. The responsive actuator, integrated pressure transducers and strain gauges provide state-of-the-art proportional control in a compact and lightweight package.
- Up to 10,000 psi: Capable of performing even under extreme use cases
- Multi-functional operation – isolation and regulation: Provides greater versatility over other units
- < 0.5 millisecond operation: Rapid response guarantees precise control
Submersible Solenoid Valves
Our patented solenoid valve technology features the Marotta-originated balanced-poppet design. These cost efficient solenoid valves are available in a variety of sizes, pressures and flows. Available in 2-, 3-, and 4-way brass body or stainless steel materials.
- Submersible designs: Capable of use underwater
- Suitable for hydraulic and pneumatic, light oil: Offers numerous options for operators
- Ease of maintenance: Cuts down on time spent servicing the unit
In-Line Valves
This unique multi-function, high-flow technology features a distinctive coaxial flow path that offers a significantly lower pressure drop compared to conventional submarine valves of similar size. Can be used as either a check valve, shut-off valve, reducing valve or relief valve.
- Space-saving axial flow configuration: Conserves space in tight quarters
- Reduces manpower requirements: Keeps crew members focused on other tasks
- Piloted or motor operated: Multiple options for maximum compatibility
Pressure Reducers & Regulators
Available as lightweight stand-alone valves or as cartridge designs, our single-stage pressure reducers cove a wide range of regulated outlet pressures. Marotta regulators offer an integral relief valve to accurately maintain system pressure.
- Protect against over-pressure: Prevents equipment failures
- Wide range of flows and pressures: Easy compatibility for multiple use cases
- Eliminate “diaphragm fatigue” failures: Extends the lifespan of equipment
