Whale Non-Return Valve – prevents backflow in pump and hose systems

No backflow, no pressure loss: This non-return valve from Whale reliably maintains the water column in the suction hose of your on-board pump. This means the pump does not have to re-prime with each pumping operation – saving energy and protecting the mechanics.

Tip: Pay attention to the flow direction – non-return valves are marked with an arrow. Before installation, check whether the valve is suitable for the respective outer or inner hose dimension standard.
