Specializing in non-slamming check valves with a low loss design.

Norvea’s nozzle check valves are ideal for applications where the reverse flow of a liquid has to be avoided. These valves are suitable for all kinds of liquid and gaseous fluids and are fire-safe by design. Typical applications include pipelines, steel mills, chemical plants, water works, pumping stations, water distribution plants, compressor stations, to name but a few.

Noreva’s NRV-B owes its distinctiveness to the design of the ring-shaped valve disc, which is guided resistant-free by helical springs and radial guides, insuring a water hammer free closure of the valve, despite rapid velocity changes. This design also results in very low pressure losses due to two ring-shaped annular flow passes.
