GROCO 2" Bronze In-Line Check Valve

The GROCO 2" Bronze In-Line Check Valve is a one-way flow control device designed to prevent backflow contamination in marine water systems. This valve is essential for applications such as raw water cooling, washdown systems, and live wells, ensuring that unwanted reverse flow does not compromise engine integrity or introduce saltwater into freshwater tanks.

Constructed from marine-grade bronze, the GROCO CV-200 is built to resist corrosion in harsh saltwater and brackish environments. Its internal flapper mechanism allows for smooth operation under normal forward pressure while quickly sealing shut to prevent siphoning during idle or rough conditions. The in-line design facilitates easy integration into existing plumbing without the need for additional manifold space.

This valve is particularly beneficial for serious anglers and cruising boaters, providing peace of mind against the operational issues and costly repairs that backflow can cause. Installation is straightforward, allowing users to thread the 2-inch connection into existing hose barbs or flange fittings without modifications. The minimal pressure drop ensures efficient pump operation, making it a reliable choice for various marine applications.
