Frequently Asked Questions

What are marine drain valves used for?

Marine drain valves are used to remove water from ship decks, hatch covers, scuppers, and other areas where water may accumulate. They provide a controlled, watertight drain point that helps prevent water damage and ensures safe operations at sea.

How do I choose the correct drain valve size?

Select a valve size based on the required flow rate and the deck thickness where it will be installed. Common sizes for deck drains range from 1/2 inch to 2 inches. If you are unsure, consult the vessel's design specifications or an experienced marine engineer.

What maintenance do drain valves require?

Keep the valve clean and free of debris to ensure smooth operation. Periodically check the sealing surfaces for wear and lubrication of the moving parts. With proper care, these valves provide many years of trouble-free service.
