If you own a boat, you know how important it is to have reliable marine valves and seacocks that can control the flow of water in and out of your boat. Whether you need to fill your water tanks, drain your bilge, or flush your waste, you need valves that are easy to operate, durable, and corrosion-resistant. That's why Fisheries Supply offers a wide range of marine valves from top brands, including seacocks, Y-valves, ball valves, and check valves.
Seacocks are marine valves that are mounted on the hull of a boat and allow water to enter or exit the boat. They are usually made of bronze, stainless steel, or plastic (marelon) and have a lever or a handle that can open or close the valve. Seacocks are essential for safety, as they can prevent water from flooding the boat in case of a leak or a rupture.
Y-valves are marine valves that have three ports and can divert the flow of water from one source to two different destinations. They are often used for waste management systems, such as holding tanks, macerators, or overboard discharge.
Ball valves are marine valves that have a spherical element inside that can rotate to open or close the valve. They are very common and versatile, as they can be used for various applications, such as fuel lines, water systems, or hydraulic systems. Ball valves can be made of different materials, such as bronze, stainless steel, or plastic (marelon).
Check valves are marine valves that allow water to flow in one direction only and prevent backflow. They are useful for preventing contamination, siphoning, or flooding in certain parts of the boat.
At Fisheries Supply, we have all the marine valves you need for your boat. We also have knowledgeable representatives who can help you choose the right valve for your specific needs. Contact us today and get the best quality and service in the maritime industry. We also have a great selection of thru-hull fittings.
