Legacy in Shipboard Controls
Every US Surface Combatant and Submarine goes to sea with Marotta ship controls and shipboard safety valves serving in mission-critical applications. Marotta Controls designs, develops, manufactures and qualifies high-performance motion and flow control systems for surface ships, submarines and deep submergence vessels.
Our components and naval control systems meet stringent requirements and MIL standards for shock, vibration and low acoustic signature as well as resistance to seawater corrosion. We have pioneered next-generation submarine controls that use advanced materials and embedded electronics to reduce weight, life cycle cost, size and corrosion sensitivity.

Alignment Fittings
Our Flo-Fit® valves are patented shipboard fittings that eliminate pipe alignment problems, reduce stress and provide a leak-free assembly unaffected by shock, vibration or thermal distortion. Their pivoting ball-and-socket design enables these naval valves to compensate for pipe misalignment, reducing stress and maintaining leak-free performance under vibration and thermal distortion.
- Non-restricted flow path
- Line pressures up to 10,000 psig
- Compact size for simplified installation and handling
Auto-Stop / Excess Flow Valves
Flo-Fuse® naval valves can tolerate overloads up to 100% above normal flow settings. A built-in dashpot feature absorbs transient pressure surges of substantially greater magnitude. In the event of excessive flow, the Flo-Fuse shipboard pressure control valve closes instantly – stopping flow and/or escaping line fluid. This isolates downstream failures while tolerating temporary overloads.
- Re-settable feature
- Available “In-Line” or “Y” configurations
- Adjustable shut-off flow
Chilled Water Solenoid Valve
An engineered solution to prevent water intrusion into the solenoid, this technology meets the requirements of MIL-STD-108E for splash-proof and for submersible applications. Also available with Intelligent Fluid Control Electronics for distributed system control. This design is intended for submersible shipboard environments, maintaining reliable operation at low pressure differentials while supporting distributed shipboard control systems through optional integrated electronics.
- Sizes available from 3/8″ to 2
- Operates with pressure differentials as low as 3 psid
- Polypropylene poppet for long life and bubble tight sealing
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 valves of similar size. It can be used as a check valve, shutoff valve, reducing valve, or relief valve.
- Space saving axial flow configuration
- Reduces manpower requirements
- Piloted or motor operated
Valve Manifolds
Manifold offerings range from simple single inlet to multiple outlets, to multi-chambered flow control units. Our shipboard manifold systems are of single block or “building block” construction, and all valving is plug-in type. Because they integrate multiple shipboard valves and regulators into a single unit, they reduce installation complexity, minimize leak paths, and improve configuration control.
- Configuration control
- Space-saving designs
- Quieting manifold technology
Motor Operated Pilot Valve
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. They feature corrosion-resistant materials and modular construction to deliver long service life, leak-tight performance, and simplified maintenance in contaminated seawater environments.
- Resists seawater corrosion
- Solid-state electronics
- 25 year service interval
Quick Closing Valves
The SPV82 Quick Closing Valves series provides a simple overriding release mechanism that enables emergency closing or opening in milliseconds. When an emergency occurs, a lever actuates the armed release mechanism, closing or opening the valve without manually turning the hand wheel. This means they can support fire prevention and system protection with options for zero-leakage sealing and remote actuation.
- Emergency opening/closing in milliseconds
- Packless construction (bellows seal)
- Visual position indication (closed-open)
Frequently Asked Questions
What are shipboard controls and why are they critical?
Naval control systems are integrated systems for managing fluid, gas, and pressure across platforms. Because of their importance to propulsion support systems, safety systems, and operational systems, these fluid and gas flow control solutions must provide maximum reliability in marine environments subject to shock, vibration, and corrosion.
How do integrated shipboard control components improve system reliability?
The integrated design of these naval control systems helps reduce leak paths and failure points. This level of engineering ensures improved performance consistency, and their modular or cartridge-based components also help simplify maintenance.
What standards must shipboard control systems meet?
These gas and fluid control systems must meet military standards (MIL-STDs) for shock, vibration, and environmental exposure. Our controls feature designs and materials selected to meet corrosion resistance and durability requirements.
