Maritime Control & Thermostatic valves
Mar-In Controls B.V. supplies a wide range of maritime control and thermostatic valves designed to withstand the demanding conditions at sea. These valves ensure reliable operation in shipboard cooling, heating, fuel, and propulsion systems, offering both safety and efficiency. Built with durability and precision in mind, our valves deliver long-term performance on vessels of all types.
Reliable valve solutions for maritime systems
Ships operate under constant pressure and varying environmental conditions. Control and thermostatic valves are critical to maintaining system stability, especially in applications such as fuel management, cooling systems for diesel engines, and automation of onboard processes.
Our valves are available in different configurations, including globe valves (2-way and 3-way), plug type, butterfly, and diaphragm valves. Each solution is designed for heavy-duty maritime use and can be integrated with onboard control systems for seamless operation.
