VALVES
Fairbanks Morse Defense delivers a complete naval valve portfolio — from build-to-spec standard valves to application-engineered solutions designed around your toughest requirements. One source for submarine and surface ship flow control, backed by decades of severe-duty engineering.
LEADING THE WORLD IN VALVE TECHNOLOGY
Every valve in the portfolio is built to perform in the harshest shipboard environments. Whether you choose a built-to-spec product or an application-engineered solution, you get the same foundation: severe-duty design, proven materials, and support across the full service life of your fleet.
- Severe-duty performance for the pressures, shock loads, and operating demands of naval service
- Submarine and surface ship applications across new build, retrofit, and fleet sustainment
- Corrosion-resistant materials — including nickel aluminum bronze, stainless steel, titanium, and other naval-grade alloys
- Critical media compatibility spanning seawater, fuel, oil, steam, and hydraulic systems
- Manual and actuated configurations with remote and hydraulic options to fit your system architecture
- Full lifecycle support from engineering and manufacturing through testing, service, and aftermarket parts
Explore our Naval Valve Solutions
Fairbanks Morse Defense supports a broader naval valve portfolio built around how your program actually works. When a system calls for a proven, repeatable valve type, you can move quickly with products built to required standards. When an application pushes beyond standard configurations, our engineers develop a solution around your operating conditions and performance targets. Either way, you work with one source across submarine and surface ship platforms, backed by severe-duty engineering and support across the full service life of your fleet.
Built-to-Print Valve Solutions
These valves are manufactured to established naval specifications and approved drawings, giving you a dependable solution for repeatable shipboard applications. When a system calls for a proven valve type, you can move quickly with products built to known standards. This is the right solution for sustainment, replacement, and configurations your program already relies on.
- Replacement and sustainment for established valve types across submarine and surface ship fleets
- Repeatable configurations built to required naval specifications and drawings
- Known system requirements where the design and performance are already defined
- Efficient sourcing for standard shipboard applications and ongoing fleet support
Application-Engineered Valve Solutions
These valves are engineered around your application, with the design shaped by media, pressure, temperature, footprint, and mission demands. When standard configurations fall short, our engineers develop a solution to meet your specific operating conditions. This is the solution for specialized programs that need performance tailored to a unique challenge.
- Mission-specific applications that require a valve designed for the task at hand
- Custom performance requirements across pressure, temperature, media compatibility, and flow
- Actuation options including manual, remote, and hydraulic configurations
- Unique shipboard constraints such as tight spaces, severe-duty service, and specialized system architecture
