Valves for ships, engines and drive units and conveying raw materials and generating energy on the high seas need to function reliably and have a long service life, even under extreme conditions.
The sea not only demands optimal performance from people, but also from machines and material. Valves must withstand huge pressure drops, high temperatures and high solid fractions, or even a combination of these factors. In addition, sea water corrodes materials almost immediately and aggressively. The grand dimensions of ships and their drive units also require specialist technology. They need to be able to apply enormous forces over a long period of time, but simultaneously steer smoothly and precisely. Selecting the correct materials and appropriate construction are crucial in assuring reliability and service life.
Valves are been designed, tested and manufactured under arduous conditions and available in a wide choice of materials to meet the most aggressive marine corrosion environments.
