Whale Water Systems In-Line Check Valves for Marine Applications
Now a proud part of Navico Group (a division of Brunswick Corporation), Whale is a committed leader in connected water systems for marine applications, and their in-line check valves exemplify the engineering precision that boaters have relied on for decades. These non-return valves serve a critical function in marine plumbing systems, preventing backflow and maintaining prime in both suction and discharge lines across bilge, freshwater, and waste water installations.
Engineered for Marine Reliability
Whale check valves reliably maintain prime in a suction or discharge line and prevent drain back so a line is always ready for pumping. The Whale Water Systems approach to valve design emphasizes durability in harsh marine environments, with nitrile construction that resists saltwater corrosion and maintains elasticity across temperature fluctuations. All Whale bilge switches, non-return valves, strainers and pipework fittings are designed and manufacturers with highest quality at heart, ensuring these components integrate seamlessly into complete marine plumbing systems.
Product Line and Versatile Sizing
The Whale in-line check valve range covers multiple hose diameter requirements, from compact 1/2-inch models for smaller systems to larger stepped-connection valves accommodating 1-inch through 1-1/2-inch applications. Popular models include the LV1215 stepped connection valve for 25mm/38mm (1"/1-1/2") hose, the LV1218 for 25mm/28mm installations, and the LV1219 for 3/4-inch to 1-inch applications. These inline non-return valves can be installed in manual or electric pump systems to help maintain prime and prevent back flow, making them adaptable to diverse onboard water management needs.
Construction Features and Installation
Whale check valves feature rigid ABS plastic body with chrome brass, phosphor bronze spring, and nitrile seal components that deliver long service life in demanding marine conditions. The valves are designed for straightforward in-line installation using either hose clamps or PVC fittings, compatible with both manual and electric pump configurations. The Whale valves offer a simple way to prevent back-flow and maintain prime in a suction or discharge line, representing practical solutions for bilge systems, freshwater delivery, and deck wash applications where consistent flow direction is essential for system performance.
