Aventics R417002149 Magnetventil 24VDC | Marine Solenoid Valve – New

Aventics R417002149 Magnetventil 24VDC – NEW

The Aventics R417002149 is a 24VDC directional control solenoid that connects a vessel’s PLC logic to its physical pneumatic architecture. This equipment doesn’t just manage the air; it also sends signals to engine room manifolds, propulsion control loops, and heavy-duty deck gear from a distance. It was built expressly to meet the quick-response needs of auxiliary air-handling circuits, making sure that digital commands from the bridge or ECR are turned into immediate mechanical movement across the ship’s pneumatic bus.

In a marine setting, reliability isn’t about how well something works in a clean room; it’s about how well it can handle the 24/7 heat cycling and structural harmonics of an active engine room. The R417002149 is designed to keep the timing accurate even when the main engine is vibrating at a low frequency all the time.

Technical Specifications

Routine Maintenance Guide

1. Check the coil resistance by taking Ohmic readings from time to time to see if there is any internal shorting or damage to the solenoid winding before it breaks down altogether.
2. Listen for leaks in the pneumatic ports, especially the exhaust ports, to make sure the seal is still good. Particles entering inside can produce internal blow-by, which can show up as these leaks.
3. Tightness of the electrical connection: Marine vibrations might loosen terminal screws, so ensure sure the DIN connector is correctly torqued and the gasket is in place.
4. Check the air quality: The air that comes in should be filtered to at least 40 microns and dried so that it doesn’t stick inside the valve spool.

Our Engineer Tips:

One specific issue often encountered by ETOs and Engineers is the Ghost Leak—where a valve fails to shift or resets intermittently despite receiving a 24V signal. In the marine sector, this is frequently caused by residual magnetism or back-EMF in long cable runs between the control room and the engine room. If you find the R417002149 is hanging in an energized state, check your suppressor diodes. We recommend installing a surge protection connector at the valve head to ensure the magnetic field collapses instantly, preventing timing errors in critical interlocks.

Applications

• Main Engine Control: Control of the beginning and stopping sequences of the air.
• Ship Automation: Using pneumatic actuators to control ballast water valves and fuel oil separators.
• Auxiliary Systems: Control of air-start motors for emergency generators.
• Deck Machinery: Winches and pneumatic brake devices can be controlled from a distance.
