The KPM-Marine Non-Return Valve has been designed to ensure maximum flow from the Predator pump. CNC machined from aluminum. Hard anodized and powder coated the valve is the most robust on the market. The flapper valve is maintenance-free and made from water board approved EPDM for extra life. Sizes available: 1”, 1.5” and 2” pipe inside diameters. The unit has a very low crack pressure and virtually zero effect on flow. The NRV is easily repairable by simply fitting a new gasket flapper. Like all KPM repairability engineering, the gasket can be turned over to reveal a new sealing surface. This NRV should last you a lifetime.
