Whale In-Line Non-Return Valve

The Whale In-Line Non-Return Valve (model LV1219) is an essential safety component for marine plumbing systems where backflow prevention is crucial. This valve is designed for various applications, including galley freshwater systems, waste discharge lines, and engine cooling loops, ensuring that water flows in one direction only.

Utilizing a simple poppet mechanism, the Whale valve opens under positive pressure and seals instantly when pressure reverses, effectively preventing backflow without restricting normal flow. Its compact design and lightweight construction facilitate easy installation in tight spaces, making it ideal for engine bays and below-deck plumbing.

This versatile non-return valve is suitable for both freshwater and saltwater systems, appealing to liveaboard cruisers and weekend anglers alike. It is compatible with electric or manual pump systems, ensuring reliable performance across a range of vessels from small fishing boats to larger cruising sailboats.
