Marine actuation systems play a vital role in ship operations by controlling valves, hatches, and other mechanical components. These systems consist of actuators, control valves, and associated piping and instrumentation. Actuators are the key components that generate motion and include hydraulic cylinders, electric motors, and pneumatic devices. Proper selection and maintenance of actuators and valves is crucial to ensure safety, performance, and regulatory compliance of marine vessels.
Hydraulic actuators are one of the most commonly used actuator types in the Marine Actuators and Valves industry. They can generate very high forces and are well-suited for applications that require reliable operation in harsh environments. Hydraulic systems comprise hydraulic pumps, cylinders, valves, piping, and reservoirs. Hydraulic cylinders provide linear motion and are often used for hatch covers, ramps, tunnel thrusters, and emergency shutdown systems. Key considerations for hydraulic actuators include power requirements, operating pressure, and cylinder stroke length.
