GROCO 1-1/2" Bronze In-Line Check Valve

The GROCO 1-1/2" Bronze In-Line Check Valve (Model CV-150) is a marine-grade one-way flow control device designed for seawater and freshwater cooling systems, raw water intakes, and through-hull applications where backflow prevention is essential. This valve is crucial for any skipper looking to protect their vessel from unwanted reverse flow that can lead to flooding or engine performance issues.

Constructed from durable bronze, the CV-150 is built to withstand the corrosive demands of continuous marine service without leaking or sticking. Its internal flapper mechanism allows for normal forward flow while automatically closing to block reverse flow, ensuring reliable operation without the risk of jamming or requiring external power. The valve opens at minimal pressure differential, optimizing the efficiency of your cooling or intake system.

Ideal for protecting an engine's fresh water cooling loop or preventing siphoning through a through-hull fitting, this check valve is compatible with standard marine hose and fittings. Weighing 1.5 lbs, installation is straightforward on any existing 1-1/2" marine plumbing run, making it a practical choice for boaters looking to enhance their systems.
