Beckson Marine In-Line Check Valves
Beckson Marine In-Line Check Valves: Reliable Flow Control on the Water
When it comes to dependable marine plumbing hardware, few names carry the weight of experience that Beckson Marine does. Founded in 1955, Beckson pioneered the use of plastics in marine hardware at a time when the industry still relied heavily on metal components — and that spirit of innovation has carried through to every product in their lineup, including their in-line check valves.
An in-line check valve may be a small component, but its role in a well-functioning marine plumbing system is critical. Positioned within a hose run, it acts as a one-way gate: allowing fluid to flow freely in the desired direction while preventing backflow that can drain a pump's prime or allow unwanted fluid migration through your system. This is especially important aboard vessels where pumps must lift fluids over a significant vertical distance — a scenario commonly described as high suction head — where even a momentary loss of prime can be a serious inconvenience or hazard.
What Makes Beckson's In-Line Check Valves Stand Out
Beckson's in-line check valve offering is purpose-built for marine hose applications, particularly for use with their own flexible hose lines. The CV-1-1/2 (model CV112) is sized for 1-1/2" flexible hose and is designed to be compatible with Beckson FH-1-1/2 or VCS-1-1/2 hose — a thoughtful system-level consideration that simplifies installation and ensures a secure, leak-free connection. The valve is constructed from ABS plastic, the same category of marine-grade materials that Beckson helped popularize in the industry for their inherent resistance to corrosion, electrolysis, and the constant moisture exposure that metal fittings struggle with over time.
Inside the valve, a flat flapper mechanism serves as the check element. Flapper-style internals are well-regarded in marine settings because they open with minimal resistance under forward flow and seal decisively against backflow, making them efficient partners for hand pumps and bilge systems alike. The result is a valve that reduces back pressure while simultaneously preventing the fluid from reversing course when pumping stops — helping to maintain prime and reduce the number of strokes needed to move fluid through the system.
Trusted by Boaters, Built for the Marine Environment
Beckson's reputation for quality stems from over six decades of real-world marine testing. Their products are designed and built to withstand the rigorous demands of the marine environment, and their in-line check valves are no exception. Rather than being an afterthought accessory, these valves are engineered as an integrated part of Beckson's broader pump and hose ecosystem — which means they work seamlessly alongside Beckson's well-known hand pump lines.
For anyone maintaining or upgrading marine plumbing systems, pairing a Beckson in-line check valve with compatible hose and pump components ensures that every part of the fluid path is designed to the same marine standard. Whether you're re-plumbing a bilge system, servicing a washdown circuit, or improving pump efficiency below decks, Beckson's check valves are a straightforward, proven solution.
