Valves for shipbuilding – For maritime applications that stand the test of time
What you regularly face in shipbuilding
Different rules apply on the high seas. Materials are constantly exposed to salt water, systems must function reliably even under heavy use, and maintenance cycles are often long. This is precisely where components that think for themselves—and work with you—come into play.
In shipbuilding, technical decision-makers regularly face questions such as:
- How can media management on board be designed to require as little maintenance as possible?
- Are there corrosion-resistant valves for fuel, waste water, or ballast water?
- How can I connect existing control systems easily and securely?
These challenges require not a standard solution, but adaptable technology—for every functional unit on board.
Our valve solutions for the maritime sector
We offer you a valve system that adapts to your maritime application—not the other way around. With our modular system, we configure valves that are specifically tailored to the requirements of ship operation.
Whether media changes with varying pressure, aggressive or temperature-sensitive substances, confined spaces, or demanding control concepts: our coaxial valves, control and regulating valves, and ball valves are ideal for maritime use—durable, compact, and ready for action.
What makes our valves special in shipbuilding
- Media-separated designs for ballast water, fuel, wastewater, CO₂, seawater
- Materials such as stainless steel 1.4571, PVDF, or nickel-plated steel—ideal for saltwater environments
- Servo-controlled variants for controlled flow with complex control systems
- Compact dimensions for tight installation spaces in machine rooms or supply lines
- ATEX-compliant options for flammable gases and hazardous areas on board
- Long-term sealing thanks to coordinated sealing materials – even with frequent shifting
- Can be integrated into onboard digital control systems (e.g., PLC or BUS)
Where our valves are used in the maritime environment
-
Ballast water management
Plastic valves with a media-separating function regulate the water supply to tanks – corrosion-resistant and easy to clean. -
Fuel circuits on ocean-going vessels
Metal valves with PTFE seals enable safe opening and closing even with diesel, heavy fuel oil, or LNG—regardless of environmental influences. -
Air conditioning systems on passenger ships
Coaxial valves control the CO₂ refrigerant circuit in central cooling units – with high switching power and speed. -
wastewater and drainage systems Robust ball valves and check valves regulate the outflow—even under difficult pressure conditions.
Why this technology works at sea
Our valves are not developed in a laboratory, but in dialogue with applications where perfect conditions are not important, but rather technology that works – always.
The combination of modular technology, experience-based material selection, and integrated control connection makes our products a reliable component in any maritime system. We do not supply you with a product that can be "installed somehow," but rather with solutions that fit into your design—mechanically, in terms of control technology, and economically.

FAQ – Valves for maritime applications
Yes. Our metal and plastic valves are designed for continuous use in saline conditions. Stainless steel 1.4571 and PVDF in particular can withstand the corrosion exposure at sea over the long term.
From fuels, CO₂, wastewater, and coolants to air, nitrogen, and process water—we provide the right combination of material, geometry, and control.
Our control valves can be controlled electrically, pneumatically, or servo-controlled. Feedback devices, sensors, or BUS interfaces can be added or integrated directly.
Yes. For all areas where explosion protection is required—e.g., gas or oil pipelines—we offer tested ATEX versions with the relevant documentation.
Standard solutions are usually available at short notice. Thanks to our warehouse and our own production facilities, we can also quickly produce custom-made products—usually within a few working days.
For areas such as drinking water supply or food preparation, we offer dead space-free, hygienic solutions with smooth internal geometries and suitable materials such as PTFE or PVDF.
