Marine Industry Valve Solutions

At EMS Vana, we utilize advanced finite element analysis (FEA) throughout our engineering processes. This approach enables digital simulation of the forces that valves may encounter in marine environments before production begins, ensuring design robustness from the earliest stage.

The starting point of our design process is the simulation of every structural component. This advanced engineering methodology evaluates material stress, deformation risks, reaction forces, and residual strains, delivering maximum safety for customers seeking marine industry valve solutions. Our journey, which began in a small workshop in 1979, continues today with a highly skilled team operating in a total area of 15,000 m², comprising 5,000 m² of covered and 10,000 m² of open space. This production capacity allows fast and flexible manufacturing for large-scale ship projects and shipyard demands.

Our customer-centric approach forms the foundation of our strong market position. With decades of manufacturing expertise and a qualified workforce, we respond to even the most complex requirements of shipbuilding engineers and procurement professionals with a commitment to delivering the “best-fit solution.” We fully recognize the value of time in the marine industry and accelerate your processes through flexible product and service presentation models.

Main Valve Types Used in Marine Applications and Their Features

Selecting the correct valve for marine applications directly impacts vessel lifespan and crew safety. Forged valves in the EMS Vana product range provide superior performance in ship steam lines requiring high pressure and temperature resistance. Our forged gate, globe, and check valves are ideal for confined ship engine rooms thanks to their compact design and high sealing performance. In addition, our forged strainers prevent particulate ingress in seawater intake lines, extending equipment service life.

Ball valves, with their rapid open-close functionality, are widely preferred in emergency intervention lines and fuel systems. Our ANSI- and DIN-compliant trunnion-mounted and floating ball valves deliver industry-leading sealing performance. Trunnion-type valves, in particular, enable low-torque operation under high-pressure conditions, ensuring operational convenience.

Check valves, which prevent reverse flow, are indispensable components of bilge and ballast systems. Our swing check valves and dual plate check valves can be safely used in both vertical and horizontal pipelines. Designed to optimize onboard fluid control and minimize pressure loss, these products are comprehensively tested in EMS Vana’s ISO 17025 accredited laboratories.

Rigorous Testing Procedures and Certification

When providing valve solutions for the marine industry, quality control constitutes the most critical phase of our production. All testing and inspections at EMS Vana facilities are carried out meticulously in accordance with API 6D, API 598, or customer-specific standards. Client representatives or independent Third-Party Inspectors may directly witness test procedures, reflecting our commitment to transparency.

Our quality assurance department performs the following critical inspection and testing processes under the supervision of ISO 9712 certified personnel:

• Positive Material Identification (PMI): Chemical composition analysis, visual, and dimensional inspections.
• Mechanical Tests: Tensile, hardness, and impact tests, along with metallographic examinations.
• Non-Destructive Testing (NDT): Visual inspection per MSS SP-55, dye penetrant (PT), magnetic particle (MT), ultrasonic (UT), and radiographic (RT) testing.
• Tightness Tests: Vacuum leak testing and acoustic emission diagnostics to ensure 100% sealing integrity.
• Pressure Tests: All valves undergo hydrostatic testing above their rated working pressure.
